Carbide-tipped. For wood screws. 2-Wing. Slow spiral. HSS M2 DIN 338 fully ground drill.

Used to countersink holes for the heads of screws in woods, plastic, and non-ferrous materials. The 2-flute integral design ensures uniform and concentric results every time. High performance carbide tips with Aluminum Titanium Nitride (AlTiN) coating provide chip free hole edges, last at least 2 times longer than uncoated carbide-tipped, and 100 times longer than steel countersinks. Available in a wide variety of sizes, complete with the HSS M2 fully ground drill bit.

 AlTiN coating has many benefits:
 

• Extra wear resistance
• Allows for faster feed and speed rates
• Cutting edge protected from wear
• Better chip evacuation
• Less heat build up
• Superior cutting quality and extended tool life
