PRODUCT DETAILS
Looking for a heavy-duty drilling solution that performs reliably in demanding industrial environments? Our HSS Morse Taper Shank DIN345 Twist Drill Bits are engineered for deep hole drilling in metalworking, maintenance, and general machining applications. Designed according to DIN345 standards, these bits feature a robust construction, Morse taper shank, and high-speed steel composition that delivers performance, precision, and long service life.
DIN345 Standard
Manufactured in accordance with DIN345 for consistent quality, compatibility, and dimensional accuracy.
High-Speed Steel (HSS)
Made from premium-grade HSS such as M2 (6542) or M35 (5% cobalt on request), offering excellent wear resistance, durability, and heat resistance under high-speed machining.
Morse Taper Shank (MT1–MT5)
Ideal for machine tools with MT spindle sockets. Ensures strong grip, reduced vibration, and self-centering capability for better accuracy in deeper holes.
118° Standard Point Angle
Suitable for a wide range of materials including steel, cast iron, and non-ferrous metals. Optional 135° split point design available for improved centering and reduced walking.
Flute Design for Efficient Chip Removal
Optimized flute geometry ensures smooth chip evacuation and stable drilling performance even in deeper holes.
Diameter Range: 6.0mm – 100.0mm
Shank Type: Morse Taper (MT1 / MT2 / MT3 / MT4 / MT5)
Material: HSS M2 / HSS-Co (M35)
Surface Coating (optional): Black Oxide, Amber, TiN, TiAlN
Point Angle: 118° (standard) or 135° split point (customizable)
