Sgs 66471 Screw Machine Drill Bit 13/32 Solid Carbide

Product Description

The SGS 66471 is a solid carbide screw machine length drill bit designed for high-performance drilling in a wide range of workpiece materials. Built to DIN 6537 specification, it features a 13/32 inch (0.3976 decimal inch) diameter, a 135-degree drill point angle, and a proprietary coated finish applied to micrograin solid carbide. The 4.016 inch overall length and shortened screw machine body make it well suited for work in confined spaces or on screw machines and CNC machining centers where stub-length rigidity reduces deflection. Coolant-through capability supports high-feed and deep-hole applications.

The SGS 66471 is used in production machining environments including job shops, manufacturing facilities, and CNC operations requiring consistent hole quality across ferrous and non-ferrous materials. The Series 142P design targets universal workpiece materials, making it a practical general-purpose carbide drill for machinists, toolroom technicians, and production floor personnel. Its 2.165 inch flute length supports a maximum drilling depth of 2.165 inches, appropriate for the 3xD flute-to-diameter ratio of this series.

Key Features

• Solid micrograin carbide construction for wear resistance and dimensional stability
• 135-degree drill point angle with web thinning for reduced thrust and easier entry
• Coolant-through design supports chip evacuation and heat control at depth
• 4-margin geometry improves hole straightness and finish quality
• Proprietary coated finish extends tool life across universal workpiece materials
• DIN 6537 specification with straight-cylindrical shank fits standard toolholders

Compatibility

Designed as an OEM-style replacement or production tooling option for screw machine and CNC drilling applications requiring a 13/32 inch solid carbide stub-length drill conforming to DIN 6537.

Installation Notes

Installation and tool changes should be performed by qualified machinists or toolroom personnel with the machine fully powered down and locked out per applicable safety procedures. Seat the straight-cylindrical shank fully and evenly in a compatible collet or drill chuck rated for the shank diameter before securing. Verify coolant-through passages are clear and coolant supply is connected before engaging high-feed cycles. Do not exceed the recommended drilling depth of 2.165 inches for this flute length.
