Sgs 61019 Solid Carbide Jobber Drill Bit 0.1575 in

Product Description

The SGS 61019 is a solid carbide jobber-length drill bit designed for precision drilling in ferrous and non-ferrous metals, composites, and other hard materials. It carries a 4.00 mm (0.1575 inches) diameter with a 118-degree four-facet point geometry and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at entry. The bright, uncoated finish suits a wide range of general-purpose applications. Machinists, tool-and-die makers, and CNC operators working with close-tolerance hole requirements will find the micrograin carbide substrate and tight diameter tolerance of +0.0000 to -0.0005 inches particularly useful for maintaining consistent bore quality.

This bit fits general-purpose drilling operations in production machine shops, maintenance environments, and precision fabrication settings. It is suited to use in CNC machining centers, drill presses, and hand-operated drilling equipment where a straight-shank carbide bit is appropriate. The Series 101 designation follows DIN 338 standards, making it a recognized jobber-length format used across a wide variety of industrial and toolroom drilling applications. It is appropriate for operators who require tight diameter control in the 0.1500 to 0.2000 inch size range.

Key Features

• Micrograin solid carbide construction for extended tool life in hard and abrasive materials
• 118-degree four-facet point with web thinning reduces entry thrust and improves chip flow
• Tight diameter tolerance of +0.0000 to -0.0005 inches for close-tolerance hole work
• Right-hand cut with regular spiral flute and tapered web for stable chip evacuation
• Straight cylindrical shank compatible with standard drill chucks and collet holders
• DIN 338 standard jobber-length format for broad machine and fixturing compatibility

Compatibility

Designed as a DIN 338 jobber-length replacement bit compatible with standard straight-shank drill chucks, collet systems, and drill press spindles accepting a 0.1575 inch shank diameter.

Installation Notes

Installation and tooling changes should be performed by a qualified machinist or toolroom technician with the machine powered down and locked out per applicable OSHA lockout-tagout procedures. Ensure the chuck or collet is properly torqued and the shank is fully seated before operation. Carbide tooling is brittle and should not be used in applications subject to heavy vibration or interrupted cuts without confirming the setup is rigid and well-supported. Inspect the cutting edges before use and discard bits showing chipping or wear to avoid workpiece damage or tool breakage.
