Makita D-17457 9.5mm Cobalt HSS Drill Bit

Summary

The Makita D-17457 is a 9.5 mm cobalt high-speed steel (HSS-Co) drill bit designed for drilling into hard and tough materials including stainless steel, cast iron, and hardened alloys. Suited to professional tradespeople and site engineers who demand longer tool life and consistent performance under demanding conditions. The cobalt content raises heat resistance significantly beyond standard HSS, allowing higher cutting speeds without sacrificing edge retention.

Features

• Manufactured from cobalt-alloyed high-speed steel (HSS-Co) for superior hardness and heat resistance.
• Suitable for drilling stainless steel, cast iron, high-tensile steel, and other hard metals.
• 135deg split-point tip promotes accurate, self-centring penetration and reduces walking on hard surfaces.
• Precision-ground flutes provide efficient swarf evacuation and reduced cutting friction.
• Compatible with standard keyed and keyless drill chucks across corded and cordless platforms.
• Cylindrical shank for secure grip in all standard 13 mm chucks.
• Fully ground construction ensures consistent dimensional accuracy and concentricity.
