Value Collection 20803 Mechanics Drill Bit 0.213 in Hss

Product Description

The VALUE COLLECTION 20803 is a mechanics-length high-speed steel drill bit designed for general-purpose drilling in metal and ferrous materials. It measures 0.213 inches in diameter with a 3-3/4 inch overall length and a 2-1/4 inch flute length. The 135-degree split point reduces walking at startup and requires less feed pressure than a conventional 118-degree point. The oxide finish provides a degree of lubricity and surface protection during cutting operations. This bit is suited for machinists, maintenance technicians, and trade professionals who need a compact, stiff drill for drilling in tight spaces or where a jobber-length bit would flex.

The 20803 is intended for use in portable drills, drill presses, and machine tools where a straight-cylindrical shank is accepted. Its mechanics length keeps the bit rigid in applications where depth is limited and precision matters. Designed for right-hand cut operation, it is compatible with standard right-hand drill chucks. Primary workpiece materials include carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel. The spiral flute type is regular with a parallel web configuration and web thinning to reduce thrust load at the cutting tip.

Key Features

• 0.213 inch diameter with 135-degree split point for self-centering starts and reduced feed pressure
• Mechanics length at 3-3/4 inches OAL provides extra rigidity versus jobber-length bits
• High-speed steel construction handles carbon steel, cast iron, stainless steel, and high alloy steel
• Oxide coating adds surface lubricity and basic corrosion resistance
• Web-thinned parallel web reduces thrust and improves chip clearance
• Right-hand spiral flute with straight-cylindrical shank fits standard drill chucks

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with any standard drill press, hand drill, or machine tool accepting a straight-cylindrical 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 shank fully in the chuck before beginning any drilling operation and confirm the workpiece is clamped or fixtured to prevent rotation. Power down and disconnect the drill or machine before changing bits. Use appropriate cutting fluid or lubricant when drilling stainless steel or high alloy materials to extend bit life and reduce heat buildup. Wear appropriate eye protection in accordance with applicable shop safety standards.
