Import 22441 5/16 Inch Hss Jobber Length Drill Bit 118 Degree

Product Description

The IMPORT 22441 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel (HSS) with a gold oxide coating, it offers increased surface hardness and reduced friction during cutting. The bit features a 118-degree split point that self-centers on contact, reducing walking on flat surfaces without the need for a center punch. At 4.5 inches overall length with a 3.1875-inch flute length, it fits standard drill chucks and drill presses used across trade and shop applications. Machinists, pipefitters, electricians, and general maintenance techs keep this size on hand as a daily workhorse bit.

The 22441 is suited for drilling 5/16-inch holes in mild steel, aluminum, copper pipe, conduit, sheet metal, and similar materials in both shop and field conditions. The straight cylindrical shank seats securely in 3-jaw drill chucks without slipping under moderate feed pressure. Its right-hand spiral flute evacuates chips efficiently, reducing heat buildup during repeated drilling operations. Trades that regularly drill through box knockouts, brackets, strut, and structural steel will find this a standard go-to size.

Key Features

• High speed steel construction for durability across a range of base materials
• Gold oxide coating reduces friction and extends cutting life compared to uncoated HSS
• 118-degree split point promotes self-centering and reduces drill walking
• Web-thinned, tapered web configuration lowers thrust force required at the cutting tip
• Right-hand regular spiral flute provides reliable chip evacuation
• Straight cylindrical shank compatible with standard 3-jaw drill chucks

Compatibility

Designed as a general-purpose replacement or stock bit for any standard drill chuck or drill press accepting a straight cylindrical shank in the 5/16-inch diameter class.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify tightness with a chuck key where applicable. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat. Always wear eye protection and secure the workpiece with a clamp or vise before drilling. Dispose of worn bits properly as HSS tips remain sharp even when dull for cutting purposes.
