Value Collection C87745-1 Jobber Drill Bit 3/16 in Hss

Product Description

The VALUE COLLECTION C87745-1 is a 3/16 inch diameter jobber-length drill bit engineered for heavy-duty drilling in metal, wood, and general-purpose materials. Built from M7 high speed steel (HSS) and finished with a black oxide and gold oxide coating, this bit delivers solid wear resistance and heat dissipation under continuous use. The 135-degree split point geometry reduces walking on contact and lowers the thrust required to start a hole, making it a practical choice for production drilling and maintenance applications. Licensed machinists, millwrights, pipefitters, and general tradespeople commonly use jobber bits of this size and grade for layout and assembly work.

This bit is suited for drilling through mild steel, cast iron, aluminum, plastics, and similar materials in both shop and field environments. The straight cylindrical shank fits standard 3-jaw drill chucks. The regular spiral flute and tapered web configuration help evacuate chips efficiently during through-hole drilling. At 3.5 inches overall length with a 2.3125 inch flute length, it fits within the standard jobber-length range and is compatible with most portable and bench-top drill setups used in HVAC, plumbing, electrical, and mechanical trade work.

Key Features

• M7 high speed steel construction rated for heavy-duty grade performance
• 135-degree split point reduces walking and lowers entry thrust
• Web-thinned, tapered web for improved chip flow and reduced heat buildup
• Black and gold oxide coating for corrosion resistance and lubricity
• Right-hand cutting direction with regular spiral flute geometry
• Straight cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a standard jobber-length drill bit for use in any 3-jaw drill chuck accepting a 3/16 inch straight shank, including portable drills, drill presses, and magnetic base drills common in trade applications.

Installation Notes

Secure the shank fully in the drill chuck and verify concentricity before drilling. Use cutting fluid or a suitable lubricant when drilling ferrous metals to extend bit life and reduce heat. Do not exceed the recommended RPM range for the bit diameter and material being drilled. Worn or overheated bits should be replaced rather than reused, as compromised geometry increases the risk of breakage.
