Fully ground HSS is fairly common in premium quality metalworking drills, although most manufacturers deem it unnecessary over specification in woodwork tooling. FAMAG disagree, they believe that using over specified materials and manufacturing methods results in a tool that will deliver superior performance, durability and results. It took me one hole with the FAMAG 1594 series drill to work out who was right.
Usually the spiral channel that extracts the chips is a symmetrical U shape in cross section. FAMAG round over the trailing edge which increases the amount of space for waste removal by nearly 50%. The pitch is also more aggressive which also helps to keep the cutting face clear.
You don't get compressed wooden spirals stuck in the flutes with these bits, instead they eject a plume of chips as they are cutting, which means you can go to full depth as fast as you like and they still cut cleaner, cooler, faster and longer than anything else on the market.
Set of 5 pieces in a compact plastic cassette. 3, 4, 5, 6 and 8mm.

Bought these as I was looking for a set of nice brad points. Found lots of things on offer but decided to go with these - as an engineer myself I liked the idea of them being over engineered. I wasn't disappointed. Ridiculously sharp points, almost no pressure required for the bits to grab and go. Can literally feel the difference between these and my cheaper brad points - the bit pulls the drill towards the work piece. If you invest in these bits feel confident in putting away your other brad points and forgetting about them forever. Only criticism is the bit grabs and pulls with such force my chuck has trouble holding on to the bit! Guess next I'll be investing in a new drill...
