Import -20919-5 Mechanics Drill Bit 23/64 in Hss

Product Description

The IMPORT -20919-5 is a mechanics-length drill bit designed for general-purpose drilling in metal and ferrous materials. It measures 23/64 inches (0.3594 inches decimal) in diameter with a 4-3/16 inches overall length and a 2-11/16 inches flute length. The 135-degree split point geometry allows the bit to start cutting on contact without a center punch, reducing walking on hard surfaces. The high-speed steel construction handles repeated use across carbon steel, cast iron, stainless steel, and high-alloy steels. A three-flat Weldon shank prevents rotation in the chuck and is compatible with quick-change systems. The oxide finish provides light surface protection against corrosion. Right-hand spiral flutes evacuate chips efficiently during drilling operations.

This drill bit is suited for metalworking trades including HVAC, plumbing, and electrical contractors who drill through structural steel, sheet metal framing, and pipe hangers in the field or shop. The mechanics-length format offers a compact profile that works well in tight spaces common to mechanical system installations. It is also appropriate for maintenance technicians and fabricators working with carbon steel, cast iron, high alloy steel, high tensile strength alloys, and stainless steel workpieces. The general-purpose tool performance rating makes it a standard stock item for production and service environments alike.

Key Features

• 23/64 inch diameter with 135-degree split point for self-starting cuts on metal
• High-speed steel construction rated for carbon steel, cast iron, stainless steel, and high alloy materials
• Three-flat Weldon shank prevents bit rotation and suits quick-change chuck systems
• Mechanics length at 4-3/16 inches overall for use in confined installation areas
• Web-thinned parallel web configuration reduces thrust and extends cutting life
• Oxide finish provides basic corrosion resistance during storage and use

Compatibility

Designed as a general-purpose mechanics-length drill bit for use in standard drill presses, hand drills, and magnetic base drills equipped with Weldon-style chuck systems. Suitable for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, and stainless steel workpieces.

Installation Notes

Installation and use should be performed by qualified tradespeople familiar with metal drilling operations and applicable shop safety protocols. Secure the Weldon shank fully in a compatible chuck before operation to prevent slippage. Always wear appropriate eye protection when drilling ferrous materials. This bit does not support coolant-through operation and should be used with an external cutting fluid when drilling hard alloys or stainless steel to manage heat and extend tool life.
