Sgs 66588 Solid Carbide Jobber Drill 11.50 Mm 135 Deg

Product Description

The SGS 66588 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding industrial and machining applications. Built to DIN 6537 standards, it features an 11.50 mm cutting diameter, a 135-degree split point for precise entry with reduced walking, and a Ti-NAMITE-X coating that extends tool life in abrasive and hard materials. The 2-flute spiral geometry with web thinning promotes efficient chip evacuation. Coolant-through capability supports deep-hole drilling by delivering coolant directly to the cutting edge. This bit is suited for machinists, toolmakers, and production floor operators running CNC or manual drill presses and machining centers.

The SGS 66588 is intended for precision drilling in ferrous and non-ferrous metals, composites, and other hard materials common in manufacturing and fabrication environments. The straight-cylindrical shank accepts standard collet chucks and drill chucks without modification. With a flute-to-diameter ratio of 5xD and a maximum drilling depth of 56.00 mm, it is well matched to medium-depth hole applications on machining centers and drill presses in job shop and production settings.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in hard materials
• Ti-NAMITE-X coating reduces friction and extends cutting life in abrasive applications
• 135-degree split point minimizes entry force and reduces workpiece marking
• Coolant-through design delivers fluid directly to the cutting zone for deep-hole work
• Web-thinned geometry promotes chip breaking and evacuation in the flute channel
• DIN 6537 specification ensures dimensional conformance for consistent toolholder fit

Compatibility

Designed for use in standard collet chucks and drill chucks accepting a 12.00 mm straight-cylindrical shank. Fits machining centers and drill presses configured for DIN 6537 Series 142P jobber-length tooling in the 10.00 mm to 12.50 mm drill bit size range.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Confirm the machine spindle and toolholder are fully stopped and de-energized before changing tooling. Inspect the shank and collet bore for chips or damage before seating the drill. Follow the machine manufacturer and toolholder manufacturer torque and runout specifications when tightening the chuck or collet nut.
