Import BDNA--22433-1 Jobber Drill Bit 3/16 in Hss

Product Description

The IMPORT BDNA--22433-1 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. Built from high-speed steel with a gold oxide coating, it delivers improved lubricity and modest heat resistance compared to uncoated HSS bits. The 3/16 inch diameter and 3-1/2 inch overall length make it a standard reach option for most bench, drill press, and hand-drill applications. The 118-degree split point reduces walking on entry, and the web-thinned, tapered web geometry lowers thrust requirements. Licensed tradespeople and maintenance technicians working across HVAC, plumbing, and electrical trades keep this size on hand for pilot holes, sheet metal penetrations, and fixture mounting.

This bit suits residential and light commercial service work where a 3/16 inch hole is required in mild steel, aluminum, copper tubing flanges, plastic enclosures, or wood framing. The straight-cylindrical shank fits standard 3-jaw drill chucks without adapters. The right-hand spiral flute clears chips efficiently in through-hole drilling. It is sold individually and is appropriate as a replacement or supplemental addition to a jobber set when a single size is needed quickly on the job.

Key Features

• 3/16 inch diameter with 0.1875 inch decimal equivalent for precise sizing
• 118-degree split point reduces bit walking and lowers entry thrust
• Gold oxide finish improves surface lubricity and extends tool life in ferrous materials
• Web-thinned, tapered web design reduces cutting resistance
• Regular spiral flute with right-hand cut for standard through-hole and blind-hole work
• Straight-cylindrical shank fits standard 3-jaw chucks without modification

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any drill press, cordless drill, or hand drill fitted with a standard 3-jaw chuck accepting a 3/16 inch straight shank.

Installation Notes

Secure the shank fully in the chuck before operation and verify chuck key is removed before starting the drill. Use appropriate cutting fluid or oil when drilling ferrous metals to extend bit life and reduce heat buildup. Wear ANSI-rated eye protection during all drilling operations. Replace the bit if the cutting edges show visible wear, chipping, or discoloration from overheating.
