Sgs 56442 Solid Carbide Jobber Drill Bit 3/16 in 135 Deg

Product Description

The SGS 56442 is a solid carbide jobber length drill bit designed for precision drilling in demanding industrial and trade applications. The bit measures 3/16 inches (0.1875 inches) in diameter with a 135-degree split-point angle and an overall length of 3.2283 inches. It features two spiral flutes in a right-hand cut configuration and carries a Ti-NAMITE-X proprietary finish for improved wear resistance and heat management. The straight cylindrical shank and web-thinned point reduce entry force and help maintain accurate hole positioning. Machinists, tool-and-die workers, and maintenance tradespeople working in metal fabrication environments are the primary users of this bit.

This drill bit is suited for precision hole-making in ferrous and non-ferrous metals, hardened alloys, and similar materials where standard high-speed steel tooling falls short. The 5xD flute-to-diameter ratio and coolant-through design make it appropriate for CNC machining centers, drill presses, and other powered equipment where through-spindle coolant delivery is available. It is sold individually and packaged as a single unit, making it practical for job-specific procurement or single-spindle replacement needs.

Key Features

• Solid carbide construction for extended tool life in hard and abrasive materials
• Ti-NAMITE-X finish reduces friction and improves heat dissipation at the cutting edge
• 135-degree split-point angle with web-thinned geometry for reduced thrust and self-centering entry
• Coolant-through design supports through-spindle coolant delivery for deep-hole applications
• Right-hand cut, two-flute spiral configuration for efficient chip evacuation
• Maximum drilling depth of 2.08 inches (52 mm) in a single pass

Compatibility

Designed as a direct-fit jobber length drill bit for CNC machining centers, drill presses, and powered hand tools that accept a straight cylindrical shank with a 0.31-inch shank diameter in the SGS Series 142P line.

Installation Notes

This bit should be installed and operated by qualified machinists or maintenance tradespeople familiar with carbide tooling. Always power down and lock out the spindle before changing tooling. Carbide is brittle — avoid side-loading or impact conditions that are acceptable with high-speed steel bits. When using the coolant-through feature, confirm that coolant pressure and flow rate are within the machine and toolholder specifications before engaging the spindle.
