Sgs 56405 Solid Carbide Screw Machine Drill Bit 11/64 in

Product Description

The SGS 56405 is a solid carbide screw machine length drill bit designed for high-performance drilling in a wide range of workpiece materials. Built to Series 142P standards and conforming to DIN 6537, this bit features a 11/64 inch (0.1719 inch) diameter, a 137-degree drill point angle, and a web-thinned tip geometry that reduces entry force and improves chip evacuation. With 2 regular spiral flutes, 4 margins, and coolant-through capability, it is engineered for precision and productivity in production machining environments. Machinists and tooling specialists working in job shops, aerospace, or general manufacturing will find this bit well suited to demanding applications.

The SGS 56405 is intended for use in CNC machining centers, drill presses, and other rigid setups where tight tolerances and consistent hole quality are required. Its screw machine length profile — with an overall length of 2.5984 inches and a flute length of 0.9449 inches — makes it especially useful in confined fixtures or close-clearance setups. The straight cylindrical shank seats directly into standard drill chucks or collet holders. The coated proprietary finish helps resist wear during extended production runs across universal workpiece materials including ferrous and non-ferrous metals.

Key Features

• Solid carbide micrograin construction for rigidity and extended tool life
• Web-thinned drill point reduces thrust force at entry and improves hole start accuracy
• Coolant-through design supports internal coolant delivery for chip flushing and heat management
• 4-margin geometry improves bore straightness and surface finish
• DIN 6537 conformance ensures dimensional consistency with standard tooling systems
• Proprietary coated finish increases abrasion resistance during high-cycle drilling

Compatibility

Designed as an OEM-style replacement or production tooling option for setups requiring a screw machine length solid carbide drill bit with a straight cylindrical shank in the 0.1500 to 0.2000 inch diameter range per Series 142P specifications.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or tooling technicians familiar with CNC or manual drilling equipment. Ensure the machine spindle and collet or chuck are fully de-energized and locked out before inserting or removing tooling. Verify shank seating depth and runout before beginning a drilling cycle. Do not exceed the maximum recommended drilling depth of 0.9449 inches without retracting to clear chips.
