Hertel C.40W.2064 Taper Length Drill 0.8125 in Hss

Product Description

The HERTEL C.40W.2064 is a taper length drill bit designed for deep-hole drilling applications where a standard length bit cannot reach. Machined from high-speed steel (HSS) with a black oxide finish, it runs at a 118-degree point angle with a web-thinned, tapered web configuration for improved chip evacuation and reduced thrust at the cutting tip. The bit measures 10 inches overall with a 6.125-inch spiral flute length and a 0.8125-inch (13/16 inch) straight-cylindrical shank. It is intended for use by machinists and maintenance trades working on lathes, drill presses, and machining centers.

This taper length drill is suited for production and job-shop environments where extended reach is required in ferrous and non-ferrous materials. The regular spiral flute geometry and right-hand cut make it a straightforward fit in standard drill chucks and collet holders. At 1.09 pounds, it is a solid, full-size tool appropriate for stationary machine tool setups rather than handheld applications. No coolant-through capability is present, so conventional flood or manual lubrication applies.

Key Features

• HSS construction provides durability across a range of workpiece materials
• Black oxide finish reduces friction and offers mild corrosion resistance
• 118-degree standard point angle suits general-purpose drilling in metal
• Web-thinned, tapered web reduces cutting force and improves bit entry
• 6.125-inch flute length allows deep-hole reach beyond standard-length drill capacity
• Right-hand cut, regular spiral flute for consistent chip removal

Compatibility

Designed as an OEM-style taper length drill for use in drill presses, lathes, and machining centers accepting a 0.8125-inch straight-cylindrical shank.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit from the chuck or collet. Verify the shank is fully seated and the chuck is properly tightened before initiating a cut. Apply appropriate cutting fluid or coolant externally, as this bit does not support coolant-through delivery.
