This set of 3 tungsten carbide tipped countersink drill bits with low friction depth stops and M2 high speed steel brad point pilot bits are truly the best we have ever offered or tested. You can adjust the brad point bit to change the depth of the clearance hole, and you can adjust the rotating depth stop to change the depth of the countersink hole. A deeper recess is used when you want to use plugs, or you can set the depth of the recess to leave your screw flush with the surface. The 3mm & 4mm bits produce a major hole diameter of 9.5mm, for use with 9.5mm plugs. The 5mm bit produces a major hole diameter of 12.7mm, for use with 12.7mm plugs. The depth stop has a free spinning, aluminium low-friction collar that is nylon faced to prevent burning or marking of the wood surface. The collar has large openings on its side to help with the removal of chips, ensuring they do not clog.

The M2 high speed steel brad point bits offer a quick and clean cut alongside excellent chip removal, making them ideal for drilling the clearance holes. The tungsten carbide tipped countersink bits cleanly cut the recess and ensure that there is no scorching of the wood. Both the drill bits and countersinks are suited for use with softwoods, hardwoods and composite materials and they can be used in drill presses or electric hand drills.

The quick change ¼" hex shank is compatible with all ¼" hex shank quick change systems, it will ensure a secure hold that will not slip inside the chuck during use. These bits are certified to ensure dimensional accuracy and the set of 3 includes 3mm, 4mm and 5mm bits. ©

Counter sink bits with depth stop

Easy to drill in the right place with the brad point drill bit. Also drills to the correct depth for countersinking just to the depth of the screw or screw plug each time.

Countersink bits

Saw these on sale and snapped them up, absolutely love these bits love the adjustable depth coller

Chris H.
Improved my precision holes dramatically!

I’d been after these for a while so when they cropped up on sale I knew I had to go for it. If I’m honest I was only going to get one but couldn’t decide which size was best. With the price for all three this good I didn’t have to decide.

Supplied in their own smart wooden box, the quality is apparent. You get an Allen key to adjust the depth of the bit/countersink easily and the bits are nice and sharp. The depth stop is the real bonus feature here and hasn’t marked any of the pieces I’ve drilled into so far.

If you’re considering buying these I’d absolutely recommend it, it has elevated my precision drilling to a whole new level.

Spot on

Leaves a great finish in hard and softwoods and depth adjustment works well.
Have been searching for a set of metric countersunk bits for ages. So nice to have 3, 4 and 5mm rather than the imperial equivalents.
Highly recommended.

The bits are very sharp and it's a

The bits are very sharp and it's a useful item to have. Saves time changing to a cs bit. I took one start off as the rubber gasket falls out very easily.
