Hertel Y59919043 Spotting Drill 5/8 in Cobalt M-42

Product Description

The HERTEL Y59919043 is a single-ended spotting drill designed to accurately locate and initiate hole centers before full drilling operations. Built from Cobalt M-42 high-speed steel, the tool offers improved heat and wear resistance compared to standard HSS, making it well-suited for harder workpiece materials. The 120-degree point angle produces a shallow, precise seat that guides follow-up drills without walking. The bright, uncoated finish keeps tolerances tight and works across a wide range of materials. With a 0.625-inch cutting diameter, a 4.5-inch overall length, and a straight cylindrical shank, this drill is intended for use by machinists and toolroom professionals in CNC and manual drill press setups.

This spotting drill is a general-purpose tool used in metalworking and machine shop environments, both in production and maintenance settings. It is appropriate for residential shop, commercial fabrication, and light industrial applications. The right-hand cutting direction and spiral flute geometry suit standard spindle-direction setups on drill presses, milling machines, and machining centers. The 1.375-inch flute length accommodates spotting depths typical for center-locating operations prior to twist drilling, reaming, or tapping.

Key Features

• Cobalt M-42 construction provides elevated heat resistance and edge retention in harder materials
• 120-degree point angle for shallow, accurate center spotting and reduced drill walk
• Bright, uncoated finish maintains dimensional accuracy across general-purpose applications
• Spiral flute geometry with 20-degree helix angle aids chip evacuation during spotting
• Straight cylindrical shank fits standard drill chucks and collet holders without adapters
• Right-hand cut for use with conventional clockwise spindle rotation

Compatibility

Designed as an OEM-style general-purpose spotting drill compatible with standard drill chucks and collet systems accepting a 0.625-inch straight cylindrical shank on drill presses, milling machines, and CNC machining centers.

Installation Notes

Installation and use should be performed by a qualified machinist. Secure the shank fully in a properly sized chuck or collet before operation, and verify spindle speed is appropriate for the workpiece material and drill diameter. Always power down and lock out the machine before changing or inspecting tooling. Do not exceed the tool design limits by using it as a twist drill for full-depth hole production.
