Value Collection 20952 9/16 Inch Mechanics Drill Bit Hss

Product Description

The VALUE COLLECTION 20952 is a heavy-duty mechanics drill bit designed for right-hand cutting in demanding metalworking applications. Built from high-speed steel with an oxide finish, it features a 135-degree split point that reduces walking and requires less feed pressure at the start of a cut. The Weldon flat shank with three flats locks securely in compatible chucks to prevent slipping under torque. At 9/16 inch diameter with a 5-inch overall length, this bit is sized for general maintenance and production drilling tasks performed by machinists, maintenance mechanics, and trade professionals.

This mechanics-length drill bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and steel workpieces. The shorter mechanics length provides added rigidity compared to jobber-length bits, making it a practical choice in tight spaces or when drilling thicker stock where deflection is a concern. It is commonly used in maintenance, repair, and fabrication settings across industrial and commercial facilities.

Key Features

• 135-degree split point reduces bit walking and lowers required feed pressure
• High-speed steel construction handles hard and abrasive metals
• Weldon flat shank with three flats prevents chuck slippage under heavy torque
• Oxide coating provides basic corrosion resistance and reduces friction during cutting
• Mechanics length for added rigidity and control in tight or deep drilling applications
• Right-hand spiral flutes with 3-inch flute length for efficient chip evacuation

Compatibility

Designed for use with drill presses, milling machines, and hand drills equipped with chucks accepting a 1/2-inch Weldon flat shank. Suitable for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces.

Installation Notes

Secure the Weldon shank fully in the chuck so that at least one flat engages the set screw before tightening. Ensure the workpiece is firmly clamped before beginning any drilling operation. Use appropriate cutting fluid when drilling stainless steel or high alloy materials to extend bit life and manage heat. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
