Sgs 51042 Jobber Drill Bit Wire 42 Solid Carbide 118 Deg

Product Description

The SGS 51042 is a solid carbide jobber-length drill bit designed for precision drilling in demanding industrial and trade applications. Built to DIN 338 standards, this Series 101 bit features a 118-degree faceted point angle and a regular spiral flute pattern optimized for straight, clean hole entry. The micrograin carbide construction provides the hardness and wear resistance needed for drilling hard metals, composites, and abrasive materials. At 2 inches overall length with a 1-inch flute length, the 51042 delivers reliable performance in tight-clearance setups where control and accuracy are critical.

This drill bit is suited for use in CNC machining centers, manual drill presses, and handheld precision drilling operations. Its wire gauge size 42 designation, equivalent to 0.0935 inches (2.37 mm), makes it a standard choice for tapping preparation, precision fastener holes, and instrumentation work. The straight-cylindrical shank seats securely in standard drill chucks and collets without slipping under torque. The bright uncoated finish is appropriate for applications where coating-induced dimensional variation must be avoided.

Key Features

• Solid micrograin carbide construction for superior hardness and extended tool life
• 118-degree faceted point angle for accurate self-centering entry
• Web-thinned tapered web reduces thrust force and improves chip evacuation
• Right-hand spiral flute, regular helix for consistent chip flow
• DIN 338 standard compliance ensures dimensional interchangeability
• Straight-cylindrical shank fits standard drill chucks and collets

Compatibility

Designed as an OEM-style replacement or direct-fit option for applications requiring a wire gauge size 42 jobber-length drill bit with a straight-cylindrical shank in standard drill chucks and collets.

Installation Notes

Installation and operation should be performed by a qualified machinist or tooling technician familiar with carbide tooling requirements. Secure the shank fully in the chuck or collet before running the spindle, and verify runout before beginning production drilling. Carbide bits are brittle compared to high-speed steel - avoid lateral loading, interrupted cuts without proper setup, or dropping the bit on hard surfaces. Always operate within the recommended speed and feed parameters for the workpiece material and bit diameter.
