Sgs 51122 Jobber Drill Bit 11/32 in Solid Carbide

Product Description

The SGS 51122 is a solid carbide jobber length drill bit designed for precision drilling in demanding trade and industrial applications. It features an 11/32 inch (0.3438 inch) diameter with a 118-degree faceted point angle and a bright, uncoated finish. Built from micrograin solid carbide, the 51122 delivers the rigidity and edge retention needed when drilling harder materials where high-speed steel bits fall short. The straight cylindrical shank ensures secure chuck seating, and the web-thinned, tapered web geometry reduces entry force at the point. Machinists, pipefitters, electricians, and HVAC fabricators rely on this type of tooling for accurate hole production in metal and composite substrates.

This bit is suited for use in stationary drill presses, CNC machining centers, and hand-held power drills where consistent, tight-tolerance holes are required. The right-hand cut, regular spiral flute configuration handles chip evacuation effectively in through-hole and shallow-depth drilling operations. With a maximum drilling depth of 2 inches, it is well matched to typical sheet metal, structural steel, and light fabrication work encountered across mechanical trades.

Key Features

• Solid micrograin carbide construction for superior hardness and edge retention over HSS alternatives
• 118-degree faceted point with web-thinned, tapered web for reduced thrust and cleaner entry
• Bright, uncoated finish compatible with a wide range of cutting fluids and dry applications
• Regular right-hand spiral flute with 2.5-inch flute length promotes efficient chip clearing
• Straight cylindrical shank (0.3438 inch diameter) fits standard 3-jaw chucks without adapters
• Conforms to DIN 338 standard for consistent dimensional accuracy across production runs

Compatibility

Designed as a jobber length drill bit for use in standard 3-jaw drill chucks and collet systems accepting a 0.3438-inch straight shank, compatible with drill presses, milling machines, and variable-speed hand drills across industrial and trade applications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tradespeople familiar with rotating cutting tools. Secure the shank firmly in the chuck before operation and verify spindle speed is appropriate for the workpiece material and bit diameter. Always wear appropriate eye protection and secure the workpiece before drilling. Do not exceed the stated maximum drilling depth of 2 inches without retracting to clear chips.
