13PCS HSS-G M2 Twist Drill Bit Set Metal Titanium 1/16"-1/4" Hex Shank Bits Kit

☑️ ️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 centering, 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 Specifications Item Name: DIN338 Parallel Straight Shank Short Twist Drill Bits Set Material: HSS High Speed Steel 6542 / M2 Chemical Composition: W 5.5-6.75%, Mo 4.50-5.50%, Cr 3.80-4.40%, V 1.75-2.20% Production Technic: Fully Ground Point Cut: Split Point Coating: Titanium Point Angle: 135° Helix Angle: 40° HRC: 63-66 Diametral Tolerance:h8 Drilling Depth: Up to 5,0 mm Thickness Suitable For: Right Hand Cutting, For All-Purpose Use in Drilling Machines and Cordless Drills Shank Size: 1/4" Hex Shank Size 1/16"(1.59 mm), 5/64"(1.98 mm), 3/32"(2.38 mm), 7/64"(2.78 mm) 1/8"(3.18 mm), 9/64"(3.57 mm), 5/32"(3.97 mm) 11/64"(4.37 mm), 3/16"(4.76 mm) 13/64"(5.16 mm), 7/32"(5.56 mm),15/64"(5.95 mm) 1/4"(6.35 mm) 13 pieces in total
