Import -20915-5 Mechanics Drill Bit 19/64 in Hss

Product Description

The IMPORT -20915-5 is a mechanics-length twist drill bit built for general-purpose hole-making in metal and alloy workpieces. At 19/64 inch (0.5969 inch decimal) in diameter, it features a 135-degree split point that reduces walking on contact and requires no center punch on most surfaces. The high-speed steel construction handles the heat and abrasion generated in production and maintenance drilling. A three-flat Weldon shank locks securely in compatible chucks, preventing slippage under torque. This bit is sold individually with a minimum order quantity of five units.

This drill bit is suited for metalworking trades, maintenance technicians, and fabrication shops drilling through carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and similar ferrous materials. The mechanics-length body keeps the bit rigid and manageable in tight quarters or on a drill press. With a 2-3/8 inch flute length and 3-7/8 inch overall length, it fits standard drill press setups and handheld power drills equipped with Weldon-compatible chucks.

Key Features

• 135-degree split point reduces drill wander and eliminates the need for center-punching on most metal surfaces
• High-speed steel construction resists heat buildup during metal drilling
• Three-flat Weldon shank prevents rotation and slippage in compatible tool holders
• Web-thinned, parallel web configuration improves cutting efficiency and chip evacuation
• Oxide coating provides surface hardness and basic corrosion resistance
• Right-hand spiral flutes in a regular helix for general-purpose metalworking applications

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with Weldon-shank drill chucks and holders. Suitable for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, and stainless steel workpieces.

Installation Notes

Install in a Weldon-shank-compatible chuck, ensuring all three flats are engaged before tightening. Power down and de-energize any machine tool before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel or high alloy materials to extend tool life. Inspect the cutting edges and point for wear or chipping before each use.
