Magafor 81197080000 Spotting Drill 8mm 90 Pt Cobalt M-35

Product Description

The MAGAFOR 81197080000 is a single-ended spotting drill designed to create precise center spots and guide hole starts before drilling operations. Built from Cobalt M-35 (HSS-E), the tool handles higher cutting temperatures than standard high-speed steel, making it well suited for harder steels, stainless alloys, and difficult-to-machine materials. The drill features a 90-degree point angle, an 8 mm cutting diameter, and a 5.5-inch overall length. A spiral flute geometry with web thinning reduces thrust and improves chip evacuation at the tip. The bright, uncoated finish is standard for this grade and allows machinists to monitor wear visually during service.

This spotting drill is used in general-purpose machining environments where accurate hole location and consistent countersink geometry are required before a twist drill engages. It is appropriate for job shops, production floors, and maintenance operations running manual mills, CNC machining centers, or drill presses. The right-hand cut, straight-cylindrical shank fits standard ER collets, drill chucks, and toolholders sized for an 8 mm shank. Series 197 is MAGAFOR's general-purpose spotting line targeting everyday shop applications.

Key Features

• Cobalt M-35 (HSS-E) construction for improved heat resistance over standard HSS
• 90-degree point angle for accurate spot starts and pilot indentations
• Spiral flute design with web thinning reduces cutting force at the tip
• Straight-cylindrical shank at 8 mm diameter fits standard collets and chucks
• Bright uncoated finish allows visual wear monitoring in the field
• Right-hand cut, single-ended design for conventional spindle operation

Compatibility

Designed as a general-purpose spotting drill compatible with any machine tool spindle or toolholder accepting an 8 mm straight-cylindrical shank, including ER collet chucks and standard keyless drill chucks.

Installation Notes

A licensed machinist or qualified toolroom technician should install and operate this drill. Ensure the machine spindle is fully powered down and the tool is seated squarely in the collet or chuck before tightening. Verify runout with an indicator before production use, as excessive runout accelerates tip wear and degrades spot accuracy. Always apply cutting fluid appropriate for the workpiece material to extend tool life.
