Sgs 53116 Solid Carbide Jobber Drill Bit 1/4 Inch

Product Description

The SGS 53116 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding materials. Built to Series 103 specifications, this bit features a 1/4 inch diameter, a 150-degree drill point angle, and a 3-flute spiral configuration that promotes efficient chip evacuation and improved stability in the cut. The micrograin carbide construction provides the hardness and edge retention required when working through cast iron, hardened steel, steel, and non-ferrous metals. A web-thinned, tapered web design reduces thrust and improves penetration at the cutting tip. Licensed HVAC, machining, and fabrication tradespeople relying on tight tolerances will find this bit well-suited to precision work.

This drill bit is appropriate for use in CNC machining centers, drill presses, and handheld power tools where a straight-cylindrical shank can be properly chucked. Typical applications include through-hole and blind-hole drilling in cast iron, hardened steel, and non-ferrous metals across light manufacturing, fabrication, and maintenance-repair-operations environments. The 5xD flute-to-diameter ratio supports drilling to the full rated depth without excessive chip packing. The bright uncoated finish makes this a versatile choice when coolant or lubricant compatibility must be considered.

Key Features

• Micrograin solid carbide construction for extended edge life in hard and abrasive materials
• 150-degree drill point angle reduces entry burring and improves self-centering on flat surfaces
• 3-flute spiral design promotes faster chip evacuation compared to standard 2-flute geometry
• Web-thinned tapered web lowers cutting thrust and extends tool life
• Straight-cylindrical shank with 1/4 inch diameter fits standard collets and drill chucks
• Meets DIN 6539 standards for jobber length solid carbide drill bits

Compatibility

Designed for drilling cast iron, hardened steel, steel, and non-ferrous metals. Compatible with any machine or tool holder accepting a 1/4 inch straight-cylindrical shank.

Installation Notes

Install and remove drill bits only with the machine fully powered down and the spindle at a complete stop. Ensure the shank is fully seated and securely clamped in the collet or chuck before operation. Solid carbide tooling is brittle and should not be subjected to side-loading or interrupted cuts beyond the rated capability of the tool. Follow the machine manufacturer guidelines and applicable shop safety codes when selecting feeds, speeds, and coolant strategy for the workpiece material.
