Hertel H-8119C254000 Spotting Drill 1 in 90 Deg Hss

Product Description

The HERTEL H-8119C254000 is a high-speed steel spotting drill designed to create precise, accurate center points for follow-on drilling operations. With a 1-inch cutting diameter and a 90-degree point angle, this tool establishes clean, dimensionally consistent entry locations that reduce walking and improve hole accuracy in production and job-shop environments. The bright, uncoated finish is standard for general-purpose HSS tooling. Overall length is 5.375 inches. Machining professionals and tool-and-die trades use this type of spotting drill as a first-operation step before standard twist drills, carbide drills, or boring tools.

This spotting drill is suited for general-purpose metal removal applications in ferrous and non-ferrous materials where a precise drill entry point is required. The 1-inch straight cylindrical shank provides secure clamping in standard drill chucks, collet chucks, or Morse taper adapters. The spiral flute geometry with a web-thinned design helps clear chips efficiently during the spotting operation, reducing heat buildup at the cutting edge.

Key Features

• 90-degree point angle for precise, accurate drill-point spotting
• 1-inch cutting diameter with matching 1-inch straight cylindrical shank
• High-speed steel construction for durability across general-purpose applications
• Bright, uncoated finish — no coating buildup to affect dimensional accuracy
• Web-thinned design for improved chip clearance and reduced thrust force
• Two spiral flutes, right-hand cut, single-ended configuration

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and collet chucks that accept a 1-inch straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with drill press, lathe, or machining center setups. Secure the shank fully in the chuck or collet before operation and verify runout is within acceptable limits. Always bring spindle speed in line with the material and tool diameter before engaging the workpiece. Ensure the machine is fully stopped and de-energized before changing or inspecting tooling.
