Sgs 66549 Solid Carbide Jobber Drill 7.60 Mm 135 Deg

Product Description

The SGS 66549 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding production and precision machining environments. Built to DIN 6537 specification, it features a 135-degree split point angle for self-centering entry and reduced thrust, combined with a Ti-NAMITE-X coating that extends tool life in abrasive and hard materials. The 7.60 mm cutting diameter and right-hand spiral flute geometry deliver efficient chip evacuation in through-hole and blind-hole applications. Coolant-through capability supports high-speed machining operations where heat management is critical. This bit is handled by machinists, toolroom personnel, and CNC machine operators working in metal fabrication, aerospace, and precision manufacturing settings.

The SGS 66549 Series 142P drill bit is suited for drilling ferrous and non-ferrous metals, hardened alloys, and other materials that demand micrograin carbide construction. The straight-cylindrical shank fits standard drill chucks and collet systems without modification. With a 5xD flute-to-diameter ratio and web-thinned point geometry, this tool performs in applications requiring tight-tolerance hole quality. It is appropriate for use in CNC machining centers, drill presses, and manual milling setups where dimensional accuracy and surface finish are priorities.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• Ti-NAMITE-X coating reduces friction and extends tool life in abrasive workpieces
• 135-degree split point angle promotes self-centering and minimizes drill wander on entry
• Coolant-through design supports high-feed-rate machining with active thermal management
• Web-thinned point geometry reduces cutting thrust and improves chip flow
• DIN 6537 specification ensures dimensional consistency and interchangeability with standard toolholding systems

Compatibility

Designed as an OEM-style replacement and standard production drill for use in CNC machining centers, drill presses, and collet-chuck toolholding systems that accept a straight-cylindrical shank with an 8.00 mm shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom personnel familiar with CNC or manual machine setup. Ensure the machine spindle is fully stopped and power is isolated before inserting or removing the tool from the chuck or collet. Verify the shank is fully seated and the holding device is torqued to the machine manufacturer's specification before commencing drilling. Confirm coolant lines are properly routed if using the through-coolant feature, and validate spindle speed and feed rate against the workpiece material requirements prior to operation.
