Sgs 56473 Taper Length Drill Bit Wire 29 Solid Carbide

Product Description

The SGS 56473 is a taper length drill bit engineered for high-performance drilling in demanding applications. Built 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 for fast, accurate starts without center-punching. It carries a wire size 29 diameter with a flute-to-diameter ratio of 8xD, making it well suited for deep-hole work where chip evacuation and rigidity are both critical. The spiral flute geometry runs right-hand cut with a web-thinned tip to reduce thrust and improve hole quality. Coolant-through capability supports high-speed production environments. Licensed machinists, tool-and-die shops, and precision metalworking operations are the primary installers.

The 56473 is rated for universal material application, meaning it performs across a broad range of ferrous and non-ferrous metals. The Ti-NAMITE-X coating provides a multi-layer nanocomposite finish that resists wear and built-up edge in both dry and coolant-assisted cutting. With a flute length of 4-31/64 inches and an overall length of 71.99 mm (approximately 2.83 inches), the bit fits standard drill chucks with a straight cylindrical shank. The shank length is 1-49/64 inches. This geometry is common in CNC machining centers, drill presses, and manual knee mills used in job shops and production facilities. The DIN 6537 specification ensures dimensional consistency for interchangeability in tooling systems.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• Ti-NAMITE-X (TX) multi-layer nanocomposite coating extends tool life in high-heat applications
• 135-degree standard split point reduces thrust and eliminates the need for center-punching
• Coolant-through design supports high-speed, deep-hole drilling with active chip flushing
• Web-thinned tip improves penetration and reduces axial cutting force
• DIN 6537 specification ensures dimensional interchangeability
• Right-hand spiral flute with 8xD flute-to-diameter ratio for deep-hole capability

Compatibility

Designed as an OEM-style replacement and standard-production taper length drill bit conforming to DIN 6537 for use in CNC machining centers, drill presses, and manual milling equipment that accept a straight cylindrical shank. Universal material application rating covers ferrous and non-ferrous metals.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling handling. Carbide is brittle — avoid impact, dropping, or over-tightening in the chuck, which can cause micro-fractures. Ensure the machine spindle and chuck are clean and concentric before seating the shank. When using coolant-through capability, verify the machine spindle delivers coolant at the appropriate pressure for the application and material.
