Value Collection -20924-5 Mechanics Drill Bit 7/16 in

Product Description

The VALUE COLLECTION -20924-5 is a mechanics-length, high-speed steel drill bit designed for general-purpose drilling in metal and hard materials. It features a 7/16 inch (0.4375 inch) diameter, a 135-degree split point for fast self-centering starts without a center punch, and a three-flat Weldon shank that locks securely in compatible chucks to prevent slipping under torque. The oxide coating provides mild lubricity and corrosion resistance. At 4.5 inches overall length with a 2.9375-inch flute, this bit is sized for close-quarter and standard drill press work common in fabrication and maintenance trades.

This bit is suited for right-hand drilling in carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces. The mechanics-length profile keeps the bit rigid in confined spaces where a jobber-length bit would flex or chatter. It fits standard drill presses, magnetic base drills, and hand drills equipped with a Weldon-compatible end mill holder or set-screw chuck. Minimum order quantity is 5 units per order.

Key Features

• 135-degree split point starts on contact, reducing walking and eliminating the need for a center punch on most materials
• Three-flat Weldon shank resists rotation under high torque, compatible with set-screw style chucks and holders
• High-speed steel construction handles carbon steel, cast iron, stainless steel, and high alloy materials
• Oxide finish provides light lubricity and basic corrosion protection
• Web-thinned, parallel web design reduces thrust and improves chip evacuation
• Mechanics length (4.5 inches OAL) delivers added rigidity compared to jobber-length bits

Compatibility

Designed as a general-purpose replacement or stocking drill bit for use in Weldon-shank compatible chucks and end mill holders; suitable for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces.

Installation Notes

Install and tighten the Weldon shank securely in the set-screw chuck before operation to prevent bit rotation or pullout. Secure the workpiece firmly before drilling to prevent movement. Operate at the appropriate speed and feed rate for the workpiece material and bit diameter; excessive speed in hard alloys will shorten tool life. Minimum order quantity of 5 applies to this SKU.
