Value Collection 20909 Mechanics Drill Bit 13/64 in Hss

Product Description

The VALUE COLLECTION 20909 is a mechanics-length twist drill bit designed for general-purpose drilling in metalworking applications. Built from high-speed steel (HSS) with an oxide finish, this bit features a 135-degree split point that reduces walking on contact and requires no center punch on most surfaces. The straight-cylindrical shank seats securely in standard drill chucks. At 3-1/8 inches overall length, it fits compact drill configurations common in maintenance, fabrication, and production environments. The web-thinned parallel web construction reduces cutting resistance and improves chip evacuation during through-hole drilling.

This bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. The mechanics-length body — shorter than a jobber bit — provides added rigidity in tight clearance situations and reduces deflection in interrupted cuts. It is a practical choice for HVAC technicians, pipefitters, electricians, and general maintenance mechanics drilling pilot holes, conduit knockouts, and fastener clearance holes in structural or sheet metal.

Key Features

• 135-degree split point reduces bit walking and eliminates the need for center punching on most metal surfaces
• High-speed steel construction withstands heat generated during metal drilling without rapid edge degradation
• Oxide coating provides basic lubricity and corrosion resistance during storage and use
• Mechanics length (3-1/8 inches OAL) offers greater rigidity than jobber-length bits in confined spaces
• Web-thinned parallel web reduces thrust load and improves chip flow through the 1-15/16 inch flute length
• Right-hand spiral flutes compatible with standard clockwise-rotating drill drivers and drill presses

Compatibility

Designed as a general-purpose mechanics-length HSS drill bit suitable for use in standard 3-jaw drill chucks and drill press spindles accepting straight-cylindrical shanks at 13/64 inch (0.2031 inch) diameter.

Installation Notes

Use appropriate cutting fluid or lubricant when drilling stainless steel or high alloy materials to extend cutting edge life and reduce work hardening. Secure the workpiece firmly before drilling to prevent rotation. Select drill speed based on material hardness and bit diameter — lower RPM is appropriate for harder materials. Inspect the cutting edges before use and replace the bit if chipping or dullness is observed.
