RUKO SPB-DIN345-60.0mm-HSS morsekartio-kierrepora, HSS-E Co5, 60 mm, MK5

The RUKO SPB-DIN345-60.0mm-HSS is a large-diameter Morse taper shank twist drill bit engineered for demanding drilling in high-alloy steels, stainless steels, cast iron, bronze, and heat-resistant steels. Its HSS-E Co5 cobalt-alloyed high-speed steel construction provides enhanced heat resistance and wear life compared to standard HSS bits, while the ground-from-solid manufacturing ensures precise geometry and stable cutting performance at 60 mm diameter.

Highlights

• Material: HSS-E Co5 (high-speed steel with 5% cobalt) for superior hardness and heat resistance
• Standard: DIN 345, Morse taper shank (MK5) for secure, self-locking fit in machine spindles
• Cutting diameter: 60.0 mm with h8 tolerance for consistent hole sizing
• Point angle: 130° optimized for tough materials
• Right-hand cutting direction, bright uncoated finish

In daily use

This drill bit is intended for stationary drilling machines with an MK5 Morse taper socket. The large 60 mm diameter and 260 mm cutting length allow deep hole drilling in heavy workpieces, while the cobalt alloy maintains cutting edge integrity under high temperatures. The bright finish reduces chip adhesion and facilitates resharpening. The 465 mm total length provides ample clearance for deep bores.
