Sgs 51118 Jobber Drill Bit 9/32 in Solid Carbide Series 101

Product Description

The SGS 51118 is a jobber-length drill bit designed for precision hole-making in demanding materials where carbide tooling is required. Built from micrograin solid carbide with a bright uncoated finish, this bit delivers the rigidity and edge retention needed for hard metals, composites, and similar materials. The 118-degree faceted point and web-thinned, tapered web geometry reduce entry thrust and improve centering at the start of a cut. With a straight cylindrical shank diameter of 0.2812 inches and an overall length of 3.5 inches, the 51118 fits standard drill chucks and conforms to DIN 338 standards. It is suited for use in CNC machining centers, drill presses, and hand-held power tools.

This bit is appropriate for machine shops, toolrooms, and fabrication environments where consistent diameter tolerance and clean hole geometry are required. The two-flute regular spiral design clears chips efficiently, and the 2.125-inch flute length supports drilling depths up to 1.7 inches in a single pass. The 51118 is sold individually and is a direct fit for Series 101 tooling applications requiring a 9/32-inch diameter carbide jobber drill.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree faceted drill point with web thinning for reduced thrust and accurate entry
• Bright uncoated finish suitable for dry cutting or use with standard cutting fluids
• Regular spiral two-flute design promotes efficient chip evacuation
• Straight cylindrical shank compatible with standard drill chucks and collets
• Conforms to DIN 338 jobber-length standard

Compatibility

Designed as an OEM-style replacement and standard-fit jobber drill for Series 101 applications requiring a 9/32-inch diameter solid carbide bit with a straight cylindrical shank per DIN 338.

Installation Notes

This drill bit is intended for use by machinists and toolroom professionals in machine tool applications. Secure the shank fully in the chuck or collet before operation and verify runout with a dial indicator when tolerance is critical. Ensure the spindle speed and feed rate are appropriate for the workpiece material and carbide tooling before starting a cut. Do not use this bit as a reamer or attempt to use it in reverse rotation.
