Sgs 53118 Solid Carbide Jobber Drill Bit 9/32 Inch

Product Description

The SGS 53118 is a solid carbide jobber length drill bit designed for precision drilling in demanding materials including cast iron, hardened steel, non-ferrous metals, and alloy steel. Built to DIN 6539 standards using micrograin carbide, this bit features a 150-degree point angle that reduces entry force and improves centering on hard workpieces. The straight shank measures 0.2812 inches in diameter, the overall length is 3.5 inches, and the 3-flute regular spiral geometry promotes efficient chip evacuation. A web-thinned, tapered web configuration reduces thrust during entry. This bit is sold individually and is suited for machine shop, toolroom, and maintenance work where hole accuracy and tool life in difficult materials are priorities.

The SGS 53118 fits applications where standard high-speed steel bits fall short. The 9/32 inch (0.2812 inch) diameter and 2.125-inch flute length handle through-hole and blind-hole drilling in cast iron, hardened steel, and non-ferrous metals up to a maximum drilling depth of 1.7 inches. The bright uncoated finish is appropriate for use with cutting fluids in production environments. It is suited for CNC machining centers and manual drill presses operated by machinists, toolmakers, and maintenance technicians who require consistent dimensional accuracy.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive workpiece materials
• 150-degree point angle reduces thrust and improves self-centering on entry
• 3-flute regular spiral design promotes chip evacuation and improves surface finish
• Web-thinned tapered web lowers cutting resistance during penetration
• Straight-cylindrical shank (0.2812 inches) for standard drill chucks and collets
• Conforms to DIN 6539 dimensional standards for consistent interchangeability

Compatibility

Compatible with workpiece materials including cast iron, hardened steel, non-ferrous metals, and steel. Fits standard straight-shank drill chucks and collets sized for 0.2812-inch shanks. Belongs to SGS Series 103, covering the 0.2500 to 0.3000 inch diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or maintenance technicians familiar with carbide tooling. Carbide is brittle compared to high-speed steel; avoid side loading, interrupted cuts without proper setup, or drop impacts that can cause chipping. Secure the shank fully in a collet or drill chuck rated for the spindle speed required by the workpiece material and diameter. Apply appropriate cutting fluid for the workpiece material to manage heat and extend tool life.
