Punta centratrice HSS-Co Bosch 2608584843

HSS-Co pilot drill bit Bosch 2608584843 designed for use as a pilot in hole saws with cutting capacities under 60 mm. Manufactured from high-speed steel with cobalt for improved wear and heat resistance, it has a 1/4" hex shank and a split 135° point for accurate starts and reduced walking.

Advantages

The Bosch HSS-Co pilot drill bit combines cobalt-enhanced high-speed steel for higher hardness and temperature stability with a 1/4" hex shank for secure chucking in standard holders. The split 135° point reduces the tendency to skid on the material surface and improves centring when used with hole saws below 60 mm.

Suitable for

• Pilot drilling for hole saws with cutting diameter < 60 mm
• Drilling into metal sheets and thin sections
• Use with power drills and impact drivers that accept 1/4" hex shanks

How to use

Mount the pilot drill bit into a compatible 1/4" hex drill chuck or holder. Secure the hole saw on the arbor, align the pilot point with the intended centre of the hole, and start drilling at low speed to establish the centre. Increase speed as appropriate for the material, applying steady, moderate pressure. Withdraw periodically to clear chips and avoid overheating.

Recommendations

For best results, use appropriate cutting fluid when drilling into steel or other hard metals and avoid excessive pressure or speed to prolong the life of the HSS-Co pilot bit.
