Import 20923 Mechanics Drill Bit 27/64 in Hss Split Point

Product Description

The IMPORT 20923 is a mechanics-length, high-speed steel drill bit designed for general-purpose metal drilling in demanding shop and field environments. It features a 27/64 inch (0.4219 inch) diameter, a 135-degree split point for fast, self-centering starts without a center punch, and a Weldon flat shank for secure chuck engagement in high-torque applications. The oxide finish provides basic lubricity and corrosion resistance during use. With an overall length of 4-7/16 inches and a flute length of 2-7/8 inches, this bit fits standard drill presses, hand drills, and machining centers. It is suited for machinists, maintenance mechanics, pipefitters, and HVAC and plumbing installers who drill through structural steel and ferrous metals regularly.

This bit is intended for right-hand cutting through a range of ferrous workpiece materials including carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel. The mechanics length (shorter than a jobber bit) provides added rigidity and reduced deflection in tight spaces or when drilling through thick stock. The three-flat Weldon shank prevents slipping in compatible chucks and holders. The web-thinned, parallel-web construction reduces feed pressure and extends cutting life in production environments.

Key Features

• 135-degree split point starts on contact without center-punching and reduces walking on hard surfaces
• Weldon flat shank with three flats locks securely in compatible drill chucks and holders to prevent slippage
• High-speed steel construction handles carbon steel, cast iron, stainless steel, and high alloy steel workpieces
• Mechanics length (4-7/16 inches OAL) provides rigidity and reduced deflection versus jobber-length bits
• Oxide coating offers basic lubricity and surface protection during cutting operations
• Web-thinned, parallel-web design lowers feed pressure and extends bit service life

Compatibility

Designed as a general-purpose replacement or stock bit for use with drill presses, magnetic drills, hand drills, and machining centers accepting a Weldon flat shank in the appropriate diameter. Compatible workpiece materials include carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel.

Installation Notes

This bit is installed and serviced by machinists, maintenance mechanics, and trade professionals including pipefitters and HVAC technicians. Ensure the drill press or hand drill is powered off and unplugged before changing bits. Secure the Weldon shank firmly in the chuck or holder before beginning any drilling operation. Use appropriate cutting fluid or coolant when drilling stainless steel or high alloy steel to manage heat buildup and extend bit life.
