Hertel 02387918 Reduced Shank Drill Bit 61/64 in Hss

Product Description

The HERTEL 02387918 is a reduced shank twist drill bit designed for drilling through low and medium tensile strength materials. The bit measures 61/64 inch (0.9531 inches) in diameter with a 1/2 inch straight-cylindrical shank that fits standard drill chucks and machine spindles without requiring a larger chuck capacity. Overall length is 6 inches with a 3 inch spiral flute length. Constructed from high-speed steel with an oxide finish, this bit handles the friction and heat generated in production and maintenance drilling operations. The 118-degree standard point angle is the conventional geometry for general-purpose metalworking and fabrication work.

This reduced shank drill bit is suited for use in machine shops, maintenance facilities, and fabrication environments where operators need to run a larger diameter bit from a 1/2 inch capacity drill press, mill, or hand drill. The right-hand cut, regular spiral flute geometry efficiently evacuates chips during through-hole and blind-hole drilling in mild steel, aluminum, brass, and similar low to medium tensile strength workpiece materials. No coolant system is required for this bit.

Key Features

• 61/64 inch (0.9531 inch decimal) drill diameter with reduced 1/2 inch shank for standard chuck compatibility
• 118-degree standard point angle for general-purpose drilling in metallic and non-metallic materials
• High-speed steel construction provides toughness and heat resistance during drilling operations
• Oxide finish improves lubricity and provides basic corrosion resistance on the bit body
• 3 inch flute length with regular right-hand spiral for efficient chip evacuation
• 6 inch overall length suits both bench drill press and hand-held power tool applications

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with any 1/2 inch drill chuck or machine spindle, suitable for drilling low and medium tensile strength materials including mild steel, aluminum, and similar workpieces.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance trade professionals. Secure the 1/2 inch shank firmly in a properly rated drill chuck and verify runout before drilling. Power down and de-energize the machine before changing bits. Do not exceed the rated speed range for the bit diameter and workpiece material combination.
