Sgs 56455 Solid Carbide Jobber Drill 23/64 Inch

Product Description

The SGS 56455 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production and machining environments. Built to DIN 6537 standards, this Series 142P drill measures 23/64 inch (0.3594 inch) in diameter with a 135-degree split point and a Ti-NAMITE-X coating that extends tool life in abrasive and hard materials. The overall length is 4.055 inches (103.00 mm) with a 2.402-inch (61.00 mm) spiral flute. Coolant-through capability supports chip evacuation and heat management in deep-hole applications. Right-hand cutting with a web-thinned point reduces entry force and minimizes walking at drill start. Machinists and CNC operators in metalworking and manufacturing environments are the primary installers of this tool.

This drill bit is suited for use in CNC machining centers, drill presses, and manual machine tools requiring precision hole tolerances in ferrous and non-ferrous metals, stainless steels, cast iron, and similar hard materials. The 5xD flute-to-diameter ratio and maximum drilling depth of 1.929 inches (49.00 mm) make it well matched for through-holes and blind holes in medium-depth applications. The straight-cylindrical shank with a diameter of 0.470 inch fits standard drill chucks and collet holders. Micrograin carbide substrate provides consistent edge integrity across high-volume production runs.

Key Features

• Solid micrograin carbide construction for edge stability in hard and abrasive materials
• Ti-NAMITE-X coating reduces friction and extends cutting life
• 135-degree split point with web thinning for reduced thrust and accurate entry
• Coolant-through design supports chip clearance and thermal control in deep holes
• DIN 6537 specification ensures dimensional consistency and interchangeability
• Right-hand spiral flute with 5xD ratio for balanced chip evacuation

Compatibility

Designed as an OEM-style replacement and production-grade cutting tool compatible with standard drill chucks and collet holders accepting a 0.470-inch straight-cylindrical shank, conforming to DIN 6537 specification.

Installation Notes

Installation and use should be performed by qualified machinists familiar with CNC or manual machine tool operation. Secure the shank fully in a chuck or collet before operation and verify runout is within acceptable tolerance for the application. Coolant-through drilling requires a machine spindle with internal coolant delivery capability. Do not use this tool beyond its rated maximum drilling depth of 1.929 inches per pass without appropriate pecking cycles or chip-clearing techniques.
