Sgs 58509 Screw Machine Drill Bit 7/32 in Solid Carbide

Product Description

The SGS 58509 is a screw machine length drill bit engineered for high-performance drilling in a wide range of workpiece materials. Built from solid carbide and coated with Ti-NAMITE-X for extended tool life and heat resistance, it delivers consistent, accurate holes in demanding production and maintenance environments. The bit measures 7/32 inch (0.2188 inch decimal) in diameter with an overall length of 2.36 inches (60 mm). The 180-degree flat bottom point angle makes it well-suited for flat-bottomed hole applications where a conventional point would leave an unacceptable cone. It is installed and used by machinists, tool-and-die technicians, and maintenance professionals working with CNC machines, drill presses, and handheld power tools.

The SGS 58509 is designed for universal workpiece material applications, making it appropriate across metals, plastics, and composites in both production shop and field service settings. The screw machine length format provides a compact, rigid profile that reduces deflection in short-reach setups. With a 2xD flute-to-diameter ratio and a 19.45 mm maximum drilling depth, it is best suited for shallow to moderate-depth holes. The straight-cylindrical shank seats into standard drill chucks without adapters.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-cycle drilling
• Ti-NAMITE-X coating extends tool life and reduces built-up edge in demanding materials
• 180-degree flat bottom point angle produces flat-bottomed holes without secondary operations
• Four-margin design improves hole roundness and surface finish
• Screw machine length (compact) profile minimizes deflection in short-reach setups
• Right-hand spiral flute with straight-cylindrical shank for compatibility with standard drill chucks

Compatibility

Designed as a direct-use screw machine length drill bit for standard drill chucks and collet holders accepting a 0.2362-inch (6 mm) straight-cylindrical shank, suitable for CNC machining centers, drill presses, and handheld power tools configured for this shank size.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tool safety practices. Secure the shank fully in the chuck or collet and verify runout before drilling. Always power down and lock out the machine before changing tooling. Use appropriate cutting fluid or coolant where the machine and application permit, noting this bit does not have through-coolant capability.
