Sgs 63188 Screw Machine Drill Bit 10mm Solid Carbide

Product Description

The SGS 63188 is a screw machine length drill bit engineered for high-performance drilling in demanding materials. Built from solid carbide and coated with SGS Ti-NAMITE-A AlTiN finish, this bit delivers heat resistance and extended tool life in alloy steels and titanium. It measures 10.00 mm (0.3937 inches) in diameter with an overall length of 89.00 mm (3.5039 inches) and a 145-degree notched point angle. The web-thinned, tapered web configuration reduces entry force and improves chip evacuation. Part of the Series 135M line, this bit is suited for machinists and toolroom professionals running CNC machining centers, drill presses, or manual equipment in production environments.

This drill bit is designed for use in applications requiring precise, controlled drilling in hard or abrasive materials including alloy steels and titanium. The screw machine length format provides a shorter, more rigid profile compared to jobber-length bits, making it well suited for tight-clearance setups and high-accuracy boring operations. The straight shank and standard 10.00 mm shank diameter allow direct chuck mounting without adapters. A maximum drilling depth of 35.00 mm and a flute-to-diameter ratio of 3xD support controlled chip removal during through-hole and blind-hole operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• Ti-NAMITE-A AlTiN coating resists heat buildup when drilling alloy steels and titanium
• 145-degree notched point angle for positive self-centering and reduced thrust
• Web-thinned tapered web reduces cutting resistance at point entry
• Screw machine length profile increases rigidity versus jobber-length alternatives
• Right-hand cut with regular spiral flute for consistent chip evacuation

Compatibility

Designed as an OEM-style replacement or direct substitute for screw machine length solid carbide drill bits in the 0.3500 to 0.4000 inch diameter range, compatible with standard straight-shank drill chucks and collet systems accepting a 10.00 mm shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with carbide tooling and proper spindle speed and feed rate selection. Secure the shank fully in the chuck or collet before operation and verify runout before drilling. Solid carbide bits are brittle compared to high-speed steel — avoid lateral loading, interrupted cuts, or impacts that can cause fracture. Always wear appropriate eye protection and follow shop safety protocols when operating drilling equipment.
