Value Collection 01189182 Letter R Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01189182 is a letter R jobber-length drill bit designed for general-purpose drilling in metal and ferrous materials. Built from high speed steel (HSS) with an oxide finish, this bit measures 0.3390 inches in diameter and carries a standard 118-degree split point angle suited for a wide range of production and maintenance drilling tasks. The overall length is 4.75 inches with a flute length of 3.4375 inches. The straight cylindrical shank seats securely in standard drill chucks without requiring a collet or adapter. Licensed trades and metalworking shops reach for this bit when drilling steel, cast iron, and similar workpiece materials in everyday service conditions.

This bit is appropriate for residential and commercial maintenance, fabrication, and general metalworking applications. The two-flute regular spiral design clears chips efficiently during through-hole and blind-hole drilling in steel and cast iron. The right-hand cutting direction pairs with standard forward-rotating drill presses, hand drills, and magnetic drills. The web-thinned, tapered web configuration reduces thrust force needed at entry, making it practical for hand-drill use as well as drill-press work where feed pressure control matters.

Key Features

• Letter R size: 0.3390 inches diameter for precise fractional-equivalent hole sizing
• 118-degree standard point angle suitable for steel and cast iron drilling
• High speed steel construction with oxide coating for surface hardness and corrosion resistance
• Web-thinned, tapered web reduces entry thrust and improves centering
• Regular spiral, two-flute design promotes efficient chip evacuation
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose jobber drill bit compatible with standard drill presses, hand drills, and magnetic base drills accepting a straight shank of 0.3390 inches diameter. Primary workpiece materials are steel and cast iron.

Installation Notes

Installation and use should be performed by qualified machinists, maintenance technicians, or trade professionals familiar with rotating cutting tools. Secure the shank fully in the chuck and verify concentricity before drilling. Always wear appropriate eye protection and secure the workpiece before starting the drill. Do not exceed the rated speed for the bit diameter and workpiece material, and use cutting fluid when drilling ferrous metals to extend tool life and improve hole finish.
