Sgs 56488 Taper Length Drill Bit 21/64 in Solid Carbide

Product Description

The SGS 56488 is a taper length drill bit built for high-performance metal cutting applications where standard-length drills fall short. Manufactured from micrograin solid carbide and coated with Ti-NAMITE-X (TX) for extended tool life and heat resistance, this bit features a 135-degree split point that reduces walking and thrust force on entry. The 21/64-inch diameter and 8xD flute-to-diameter ratio make it well suited for deep-hole drilling in a single pass. Coolant-through capability supports high-speed production runs. A web-thinned geometry improves chip evacuation and reduces cutting resistance in demanding materials.

The SGS 56488 Series 142P drill bit is designed for universal material applications including steel, stainless, cast iron, aluminum, and non-ferrous alloys. It is commonly used in machine shops, fabrication facilities, and production environments where consistent hole quality and dimensional accuracy are required. The straight cylindrical shank seats in standard drill chucks and collet systems on CNC machining centers, drill presses, and milling machines. Right-hand spiral fluting provides efficient chip removal during through-hole and blind-hole operations.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance in hard materials
• Ti-NAMITE-X (TX) coating extends tool life and reduces built-up edge in universal material applications
• 135-degree split point reduces drill walk and lowers entry thrust force
• Coolant-through design supports high-speed machining and extended deep-hole runs
• Web-thinned geometry promotes chip evacuation and reduces cutting resistance
• Meets DIN 6537 specification for consistent dimensional and geometric tolerances

Compatibility

Designed as an OEM-compatible taper length drill bit for use in standard drill chucks and collet holders accepting a straight cylindrical shank; verify shank diameter and machine spindle compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully powered down and the chuck or collet is clean and free of debris before seating the bit. Confirm runout and shank seating before initiating a cut. When using coolant-through capability, verify that the machine tool coolant supply is connected and at the correct pressure for the operation.
