Features&Benefits
️HSS 6542 / M2 Material: HSS 6542/M2 is molybdenum based high-speed steel in tungsten–molybdenum series. HSS grade steel M2 is a medium alloyed high speed steel which has good machinability and features more molybdenum content(4.50-5.50%). The chemical composition gives a good combination of well-balanced toughness, high wear resistance and red hardness properties.
️Fully Ground Technic: HSS-G (ground) is cut in their shape with the help of diamond tools and cooled during the process. Use HSS-G for more precise work because they are better centered generally and perfectly symmetrical.
Split Point: For drills with very strong cores, for particularly tough, hard materials and for deep-hole drills. Split Point features good centring, little pressure required. Chip spreading improves chip removal.
135° Point Angle: The 135º high performance cutting edge ensures a very high aligned preciseness. The point angle is located on the head of the twist drill. The angle is measured between the two main cutting edges at the top. A point angle is necessary to center the twist drill in the material.The larger the point angle, the shorter the tapping time.
40° Helix Angle: The 40º helix angle enables a perfect and fast chip removal and provides a high cutting speed along with increased stability and accuracy.
️Wide Groove Profile: Wider groove profile takes a better chip absorption and removal. Poor chip removal means a higher heat development, which in return can lead to annealing and ultimately to breakage of the twist drill.
️ ️Titanium Coating: The titanium coating on the drill bit helps to reduce overheating. It’s the reason that this bit has a lifespan up to six times longer than other comparable drills.
️Applications: For light metals such as aluminum, copper, brass, bronze, plastics, hard wood and chipboard
