Double flute Straight bit

In choosing a straight bit for any application, always select one with the shortest cutting edges and the shortest overall length that will reach the required cut depth. Excessive length intensifies deflection and vibration, which degrade cut quality and lead to tool breakage.

Use a two-flute bit where fine finish is paramount. Two flutes balance the bit, eliminating vibration that degrades the cut finish.

Two cuts per revolution yield a smooth surface, but feed rate is slightly reduced.

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

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.

Fits perfectly
Size: 32mm, Color: Green
Works exactly as expected. Fits the 32mm oil filter housing perfectly and makes removal quick without slipping or rounding. Feels solid and well-made for the price. Used it for an oil change and it saved a lot of time compared to a strap wrench. Simple, effective tool—glad I bought it.

Perfect Fit 28mm Fuel Filter Socket
Size: 28mm, Color: Red
I bought the Felisbieti 28mm fuel filter socket for a vehicle maintenance project, and it worked perfectly. The fit is precise, gripping the fuel filter securely without slipping or rounding edges. The build feels sturdy and durable, with a solid metal finish that stands up to repeated use. It fits snugly on my ratchet and made removing and installing the filter much easier and faster than using adjustable tools. The only minor thing to note is that it’s specific to 28mm filters, so make sure it matches your vehicle. Overall, this socket is well-made, reliable, and a must-have for anyone doing DIY fuel filter work.

Perfect socket for the job
Size: 24mm, Color: Green, Size: 24mm, Color: Green
I purchased this 24mm socket specificaly to remove the oil filter housing on my Ram Promaster 2500 truck. Since there is limited space to get a standard socket in this area, this low profile socket was able to do the job without requiring me to loosen and push aside other components. I like that this socket is light weight, made of aluminum with large easy to read size eched into the body. the oil filter housing is made of plastic and does not require a beefy heavy steel socket. The walls on this socket are plenty thick as to cause me no concern about durability. To me, the green color is a nice touch as will be easy to spot in my socket set for the oil changes.

Perfect Tool for the Job – Compact, Durable, and Well-Made
Size: 32mm, Color: Green
I bought this 32mm oil filter socket specifically for my VW TDI, and it worked like a charm. The low-profile design is a lifesaver—there’s barely any clearance where the oil filter sits, and this tool fit in perfectly without me having to wrestle with it or remove other parts. The quality is excellent—it’s made from aerospace-grade aluminum, which means it’s both lightweight and solid. The anodized finish looks great and gives me confidence it won’t rust or degrade like some cheaper tools I’ve used in the past. The 6-point hex design grips the cap snugly and doesn’t round it off, even with decent torque applied using a standard 3/8" ratchet. I’ve already used it on a couple different vehicles (including a BMW and a Chevy) and it hasn’t slipped once. It’s a small tool, but it solves a big headache. For anyone doing their own oil changes—especially if you're dealing with tight engine bays—this socket is 100% worth it. Bonus points for the bright green color—it’s easy to find in the toolbox! Highly recommend.
