Sgs 66416 Screw Machine Drill Bit 13/64 in Solid Carbide

Product Description

The SGS 66416 is a screw machine length drill bit engineered for high-performance drilling in a wide range of materials. Built from micrograin solid carbide and coated with Ti-NAMITE-X, this bit delivers extended tool life and heat resistance under demanding production conditions. It features a 135-degree split point with web thinning for fast, accurate starts with minimal walking. The overall length is 2.5984 inches (66 mm), the flute length is 0.9449 inches (24 mm), and the straight-cylindrical shank diameter is 0.23 inches (6 mm). Coolant-through capability supports high-speed machining operations. Machinists and tool-and-die professionals use this bit where tight tolerances and consistent hole quality are required.

The SGS 66416 is suited for production drilling, maintenance machining, and precision fabrication work. Its screw machine length profile makes it a practical choice for CNC machining centers, drill presses, and manual machines where a shorter, stiffer drill body reduces deflection and improves hole straightness. The universal primary workpiece material designation means it is appropriate across ferrous and non-ferrous metals as well as many engineered materials, making it a versatile option in a general shop environment or dedicated production cell.

Key Features

• Micrograin solid carbide construction for high wear resistance and rigidity
• Ti-NAMITE-X coating reduces friction and extends tool life in demanding applications
• 135-degree standard split point with web thinning for self-centering entry and reduced thrust
• Coolant-through design supports high-feed-rate and deep-hole operations
• 4-margin geometry improves hole roundness and surface finish
• Straight-cylindrical shank fits standard drill chucks and collets without adapters

Compatibility

Designed as an OEM-style screw machine length drill bit conforming to DIN 6537, compatible with standard straight-shank drill chucks and collets accepting a 0.23-inch (6 mm) shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom professionals familiar with carbide tooling. Ensure the machine spindle and chuck are clean and free of runout before seating the shank. Solid carbide tooling is brittle and should not be subjected to side loads or interrupted cuts beyond the tool rating. Always confirm coolant flow is active before engaging the cut when using the coolant-through feature.
