Value Collection 20812 Mechanics Drill Bit 0.189 in Hss

Product Description

The VALUE COLLECTION 20812 is a mechanics-length drill bit designed for general-purpose drilling in metal and ferrous materials. It measures 0.189 inches in diameter with a 135-degree split point that reduces walking and penetrates work material with less feed pressure than a standard 118-degree point. The bit is manufactured from high-speed steel with an oxide coating for basic surface protection. At 3.5 inches overall length, it fits standard drill chucks and is sized for confined-space or close-tolerance applications where a jobber-length bit would be too long. Right-hand spiral flutes evacuate chips efficiently during through-hole drilling.

This bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. Typical applications include maintenance and repair work, fabrication shops, and field service where a compact, shorter-length bit is preferred over a jobber or taper-length equivalent. The straight-cylindrical shank seats directly in keyless or keyed drill chucks without an adapter. It is a general-purpose tool appropriate for use in hand drills, drill presses, and portable magnetic base drills.

Key Features

• 135-degree split point reduces bit walking on curved or hard surfaces and lowers required feed pressure
• High-speed steel construction handles drilling in ferrous metals including stainless steel and high alloy steel
• Oxide coating provides a baseline layer of surface protection against corrosion during storage and light use
• Mechanics length at 3.5 inches overall keeps the bit rigid and controllable in tight workspaces
• Web-thinned construction reduces cutting resistance at the center of the drill tip
• Right-hand cut with regular spiral flutes for standard clockwise drill operation and effective chip evacuation

Compatibility

Designed as a general-purpose mechanics-length drill bit compatible with any standard keyed or keyless drill chuck that accepts a straight-cylindrical shank in the 0.189-inch diameter range.

Installation Notes

A licensed machinist, maintenance technician, or experienced tradesperson should secure the workpiece firmly before drilling to prevent rotation or movement. Use cutting fluid when drilling stainless steel or high alloy steel to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and discard bits with chipped or worn tips. Always wear eye protection when operating any rotary cutting tool.
