Carbide Tipped

The double round profile router bit is designed for creating decorative mouldings or edge profiles. These cutters allow you to shape two roundovers. A bead over the top corner is possible when increasing the depth of cut. By replacing the guide bearing with a smaller diameter bearing will also allow a fillet (bead) at the bottom of the profile.

This router bit has a 6.35 mm shank (shaft) that will fit most small or large routers. Please ensure that you select a router bit with a shank (shaft) size that will fit into your router collet.

PRO-TECH router bits are manufactured in Taiwan.

 

consider safety for your health and the people around you

General safety suggestions:

It is advisable to always have the following items nearby and in a good condition

  • Eye protection clean and scratch free
  • Hearing protection quality earmuffs
  • Dust masks discard old and dirty masks
  • Gloves for easy handling of material and hand protection
Wear Gloves

Dust Mask

To use router bits safely (and to get the best results from your router), the router bits need to be installed properly into the router's collet. Improper installation of your bits can cause excessive chatter and could increase the likelihood that the bits will break when in use. 

Clean and sharp

First of all, before beginning any routing operation, check your bits to make sure that they are clean, relatively free of pitch, and most of all, sharp. If the bit is dull, chipped, is excessively burned or has any other defect, it should be sharpened or replaced before use. 

Correct collet and collet nut fit

Most router collets have a recess (groove) that needs to click into a circlip that resides inside the collet nut. Failing to ensure that the collet 'clicked' into the collet nut will cause you to struggle to remove the router bit after tightening. This could cause the collet to break or be removed by a technical repair centre.

 

Correct fit inside the collet

When installing the bit into the collet, do not tighten the collet with the bit 'seated.' Instead, insert the bit until the shank (bit shaft) reaches the bottom of the collet, then ease it out about 2 mm before tightening the collet.

When the bit is tightened, there should be no less than  2/3 's of the length of the shank in the collet. If your bit has a shank that is too short, then the bit should be replaced. 

 

Safety gear

There are a few other safety measures to keep in mind whenever you use your router. First of all, remember to always wear appropriate safety gear as indicated above.

Correct speed setting

Second, be sure to set your router to the proper speed for your router bit. Setting your router to an incorrect speed will not only affect the router's performance, but also can cause the bit to break much more easily and even cause bodily harm. The speed at which a router bit turns can be important. The typical router runs at about 22,000 rpm, which is fine for most bits. But as the diameter of the bit increases, you ll want to slow things down.

Also, before beginning any routing operation, be certain that you give the router's motor time to come up to full speed for the chosen setting. Beginning to cut before the bit is at full speed can give less than desired results. 

Observe the following at all times

  • Wear a protective face shield or Safety Glasses to prevent eye and face injury.
  • Wear ear plugs or ear muffs to protect your hearing.
  • Use a respirator or dust mask to give protection from dust particles. Wood dust may remain in the air for hours after using power tools.
  • Always read and follow router operator's manual instructions.
  • Make sure that router rpm's and the bit selected match.
  • Dress properly. Wear short sleeves, no loose fitting clothes, proper footwear and no jewellery. Tie back long hair.
  • Always be sure the router is unplugged before replacing bits and that the switch is off before connecting the router.
  • Be sure the router bit has completing stopped spinning before sitting the router down.
  • Be sure bits, clamps and attachments are secure before starting up.
  • Keep children, pets and visitors at a safe distance.
  • Be especially cautious when working small pieces.
  • Keep hands and fingers away from revolving bits and cutters.
  • Do not operate routers in moist or wet areas.
  • Always grip tool tightly and be prepared at start-up to resist the motor torque.
  • When using a router table, make sure on/off switch is easily accessible.
  • Learn the sound of your router and shut it off at any unfamiliar sounds or irregularities.
    Never start the router with the bit in contact with the material.
  • Always feed in the proper direction, against the direction of bit rotation.
  • Maintain equipment. Replace worn parts, discard worn-out bits and check router periodically. Clean parts with appropriate solvents.
  • Don't operate a tool if you are tired or under the influence of medication, drugs, alcohol or while smoking.
  • Check wood for nails, screws or loose knots before routing.
  • Keep your mind on your work, avoid distractions, work at a comfortable pace and stop before you get tired.

Do a dry run

  • Place the router on the final work surface and test you cut by moving the router over the whole are to cut with THE ROUTER SWITCHED OFF
  • You do not want to waste an expensive piece of wood
  • You do not want to start all over
  • Never met anyone with spare fingers - SAFETY

Cute backdrop for videos and room separation
Color: Black
Bought this because sometimes you need emotional boundaries AND physical ones. Surprisingly sturdy, looks nice on camera, and makes a room feel more peaceful instantly. Side note I have 2 cats and 2 large dogs and it has took a couple of beatings but did not damage at all!

Transforming Space: A Tale of Two Stunning Room Dividers
Color: Black, Color: Black
The four-panel screen room divider is absolutely stunning! Unfortunately, the first one the FedEx driver delivered ended up at the wrong address. After notifying Amazon, they promptly sent me a “replacement” room divider through UPS, which arrived right on schedule. Now, I find myself with two beautiful dividers! They both enhance the aesthetic of my home. I informed Amazon that my first room divider magically appeared today in my building’s lobby. I’ve placed one of the new screen dividers in front of an old one, and the modern Roundhill divider really makes my older piece look outdated! The Roundhill screen divider is sleek, bold, and refreshing—I’m in love with it. The second divider serves a practical purpose by hiding my bulky grocery cart, fan, and vacuum cleaner. These items used to clutter my living room closet, making it difficult to access due to the abundance of coats I had stuffed in there. Now, all those items are neatly tucked away behind the elegant Roundhill four-panel screen divider, bringing a sense of order to my space. Thanks, Amazon! ♥️ Thanks, Roundhill! ♥️

Beautiful, Sturdy, Well Made, good Value for the money
Color: Black
I don’t know what the bad reviews are about. This is a beautiful, well made 4 panel screen. The screen print appears to be a standard print that is likely the same on every screen they produce (not hand painted by two different people). It is beautiful. Everything about it, including the colors and the screen print image on rice paper, is more lovely than the photos. The wooden frame (black) is solid and sturdy. The hinges are stable and well positioned. When people say lightweight it sounds misleading. It is lightweight enough to easily maneuver but this four panel screen is sturdy and stable. It is slim and tall so someone could conceivably bump into it and jostle it. But no more so than any number of other items in one’s home. I highly recommend this beautiful, lovely, fine piece of home decor. I purchased this as a divider between my work station (office) and my living room. Also, even though there was a slight dent in the package when it was delivered, it wasn’t a deep enough gash to damage the screen. When I pulled the screen from the box my first thought was just how study it is. So very pleased with this purchase.

Beautiful Room Divider
Color: Black
This room divider is so beautiful and elegant yet very functional, study and very well made! I have had many compliments on its beauty and elegance. They have said it is much nicer than blurring my background. Which affects how you look on a teleconferencing meeting. I do zoom meetings at times for my religious meetings when I cannot go in person! And this is exactly what I have needed to obscure my private bedroom space. The size is perfect for my size desk. It covers completely the whole area not showing any of my bedroom to the public. When not in use I fold it up and put it away. It is lightweight and very easy to move around. The height doesn’t make it awkward to move and yet tall enough to obscure my whole background. MORE IMPORTANTLY~NO ASSEMBLY NECESSARY ‼️ You will not be at one moment disappointed by this purchase instead you will love it!💖💕💖
