Value Collection 01188440 No. 44 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188440 is a No. 44 wire-size jobber-length drill bit ground from high speed steel (HSS) with a black oxide finish. Designed for general-purpose drilling in steel and cast iron, it features a standard 118-degree split point and a regular spiral flute with a web-thinned, tapered web configuration. The bit measures 2.125 inches overall with a 1.125-inch flute length, making it well suited for short-reach drilling tasks in production and maintenance environments. Machinists, tool-and-die techs, and maintenance mechanics are the primary users of this size range.

This jobber drill fits applications requiring a 0.0860-inch diameter hole in ferrous metals including mild steel and cast iron. Its straight cylindrical shank seats directly in standard drill chucks and collets without adapter sleeves. Right-hand cutting direction makes it compatible with conventional drill press, lathe tailstock, and handheld drill motor setups. The general-purpose grade and oxide coating suit repetitive production drilling where frequent bit changes are expected. Coolant-through capability is not supported by this design.

Key Features

• No. 44 wire size — 0.0860 inch decimal diameter for precise small-hole work
• 118-degree standard point angle optimized for steel and cast iron entry
• High speed steel construction maintains edge integrity under moderate heat
• Black oxide coating reduces friction and provides light corrosion resistance during storage
• Web-thinned tapered web lowers thrust required at drill entry
• Straight cylindrical shank fits standard chucks and collets without adapters

Compatibility

Designed as a general-purpose replacement jobber drill for any drill press, CNC drill unit, lathe tailstock, or handheld drill motor equipped with a chuck or collet accepting a 0.0860-inch straight shank. Primary workpiece materials are steel and cast iron.

Installation Notes

Installation is performed by machinists or maintenance mechanics in shop or field environments. Secure the shank fully in the chuck or collet and tighten before powering the spindle. Wear appropriate eye protection and secure the workpiece before drilling. For small-diameter HSS bits in this size range, avoid excessive feed pressure to reduce the risk of bit breakage.
