Hertel H-8119D095207 Spotting Drill 3/8 in 120 Pt Hss

Product Description

The HERTEL H-8119D095207 is a high speed steel spotting drill designed to create precise, accurately positioned starter holes before finish drilling operations. With a 3/8 inch cutting diameter and a 120 degree point angle, it establishes a clean, centered seat that guides subsequent drill bits and reduces walkout on flat and curved workpieces. The 7 inch overall length accommodates a range of fixturing depths, while the bright uncoated finish makes it well suited for general purpose use across common workpiece materials. This tool is installed by machinists, toolroom technicians, and production floor operators working with manual or CNC drill presses and machining centers.

This spotting drill is used in general purpose metal fabrication, job shop machining, and production drilling applications. The 120 degree point angle matches the included angle of most standard twist drills, promoting accurate hole location transfer without secondary hand-deburring at the entry. The 1 inch flute length handles typical spotting depths, and the straight cylindrical shank fits standard drill chucks and collet holders in common sizes. It is a single-ended tool with a right hand cutting direction.

Key Features

• 120 degree point angle compatible with standard twist drill included angles for accurate seat transfer
• 3/8 inch cutting diameter with matching 3/8 inch straight cylindrical shank for direct chuck or collet mounting
• High speed steel construction provides toughness across a wide range of general purpose workpiece materials
• Bright uncoated finish allows visual wear inspection and suits water-soluble and oil-based cutting fluids
• Spiral flute design with 2 flutes and web thinning for reduced thrust and improved chip clearance
• Right hand cut, single ended configuration for standard spindle operation

Compatibility

Designed as a general purpose spotting drill for use in standard drill chucks and collet systems accepting a 3/8 inch straight cylindrical shank, compatible with manual drill presses, turret lathes, and CNC machining centers.

Installation Notes

A qualified machinist or toolroom technician should install this drill into a properly sized collet or drill chuck, confirming runout with an indicator before production use. Secure the shank fully within the holding device to the recommended grip length and verify spindle speed and feed rate against published HSS cutting data for the workpiece material. Power down or e-stop the machine and lock out energy sources before changing tooling. Do not use this tool for full-depth hole drilling beyond its 1 inch flute length capacity.
