Sgs 56496 Taper Length Drill Bit 27/64 in Solid Carbide

Product Description

The SGS 56496 is a solid carbide taper length drill bit from the Series 142P lineup, designed for high-performance drilling in demanding trade and industrial applications. It features a 27/64 inch (0.4219 inch decimal) diameter, a 135-degree standard point angle, and a TX coating for extended tool life and heat resistance. The spiral flute geometry and web-thinned point reduce cutting resistance and improve chip evacuation. With a flute length of 5-63/64 inches and an overall length of 161.99 mm (approximately 6.38 inches), this bit is suited for machinists and tooling professionals who require precision and durability in high-cycle drilling operations.

This drill bit is rated for universal material application, making it appropriate for use in ferrous and non-ferrous metals, alloys, and other materials encountered in production machining, fabrication shops, and maintenance environments. The cylindrical shank with an 11.99 mm shank diameter fits standard drill chucks and CNC toolholders. The right-hand cut spiral flute configuration is the standard setup for conventional drilling operations. Coolant-through capability allows for internal coolant delivery, supporting deep-hole drilling and extended run cycles. This bit follows DIN 6537 specification, confirming its dimensional and performance standards.

Key Features

• Solid carbide micrograin construction for high wear resistance and dimensional stability
• TX coating reduces friction and extends tool life in high-cycle applications
• 135-degree standard point with web thinning for reduced thrust and easier entry
• Coolant-through design supports internal coolant delivery for deep-hole drilling
• 8xD flute-to-diameter ratio allows drilling to a maximum depth of 4.4882 inches
• Conforms to DIN 6537 specification for consistent dimensional accuracy

Compatibility

Designed as a high-performance OEM-style taper length drill bit for universal material applications. Compatible with standard drill chucks and CNC toolholders accepting a cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or tooling professional familiar with carbide tooling requirements. Ensure the machine spindle and chuck are fully powered down and locked out before changing tooling. Solid carbide bits are brittle compared to HSS tooling — avoid side loading, interrupted cuts, or excessive runout, which can cause chipping or breakage. Verify coolant-through connection if using internal coolant delivery, and confirm chuck concentricity before high-speed operation.
