Hertel H-8119B095200 Spotting Drill 3/8 in 118 Pt Hss

Product Description

The HERTEL H-8119B095200 is a high-speed steel spotting drill designed to create precise, accurate starting points for follow-on twist drills and boring operations. At 3/8 inch cutting diameter with a 118-degree drill point angle, it establishes a conical seat that keeps larger drills from walking on entry. The 2-inch overall length and straight-cylindrical shank make it compatible with standard drill chucks and collet holders used on CNC machining centers, drill presses, and manual mills. Web thinning at the tip reduces thrust load and improves chip clearance at the start of cut.

This single-ended spotting drill suits general-purpose metal cutting in job shop, toolroom, and production environments. The bright, uncoated finish works well in ferrous and non-ferrous materials where coolant or cutting oil is applied directly. The 1-inch flute length and spiral flute geometry support chip evacuation in shallow spotting operations. Machinists, tool and die makers, and CNC operators are the primary end users.

Key Features

• 118-degree point angle for compatibility with standard twist drill angles
• Web-thinned tip reduces entry thrust and improves centering accuracy
• High-speed steel construction handles a wide range of workpiece materials
• Bright/uncoated finish accepts coolant and cutting oil directly
• Straight-cylindrical shank fits standard drill chucks and ER collet systems
• Right-hand cut with 2-flute spiral geometry for clean chip flow

Compatibility

Designed as a general-purpose spotting drill for use in standard drill chucks and straight-shank collet holders on CNC machining centers, drill presses, and manual milling machines accepting a 3/8 inch shank.

Installation Notes

Secure the shank fully in the chuck or collet before initiating the spindle. Confirm spindle speed and feed rate match the workpiece material and tool diameter per applicable machining data. Apply cutting oil or coolant to the cutting zone during operation. Inspect the drill point for chipping or wear before each use, as a damaged point will compromise hole location accuracy.
