Sgs 66633 Taper Length Drill Bit 5.7 Mm Solid Carbide

Product Description

The SGS 66633 is a taper length drill bit engineered for high-performance drilling in a wide range of materials. Built from micrograin solid carbide and finished with a TX coating, this bit delivers extended tool life and resistance to wear in demanding production environments. It features a 135-degree split point for accurate starting without a center punch, a spiral right-hand flute configuration, and coolant-through capability for heat management in deep-hole applications. The cylindrical shank measures 5.99 mm in diameter and seats securely in standard chucks or collet holders. This bit is sized at 5.7 mm (0.2244 inches) in diameter and conforms to DIN 6537 specification, making it a precise, reliable choice for machinists and tooling technicians.

The SGS 66633 is suited for universal material applications including ferrous metals, non-ferrous alloys, and engineered materials. With a flute length of 57 mm (2.2441 inches) and an 8xD flute-to-diameter ratio, it handles moderate to deep hole depths in production machining, aerospace component work, and precision manufacturing setups. The web-thinned point geometry reduces thrust requirements and improves chip evacuation, which is especially valuable in CNC drilling operations where feed rates and cycle times matter. This bit is sold individually and intended for professional tooling use.

Key Features

• Micrograin solid carbide construction for extended tool life in high-cycle applications
• TX coating provides wear resistance and reduces friction at the cutting edge
• 135-degree standard split point with web thinning for self-centering entry and reduced thrust
• Coolant-through design supports heat removal in deep-hole and high-feed drilling
• 8xD flute length ratio allows drilling depths up to 2.2441 inches (57 mm)
• Conforms to DIN 6537 specification for consistent dimensional accuracy

Compatibility

Designed as an OEM-compatible replacement or production tooling option for CNC machining centers and drill presses accepting cylindrical shank drill bits in the 5.99 mm shank diameter range, per DIN 6537 standard dimensions.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully powered down and locked out before changing tooling. Seat the cylindrical shank fully into the collet or chuck and verify runout before operation. When using the coolant-through feature, confirm coolant line pressure and flow rate are within the machine manufacturer specifications before running at full feed.
