Hertel 2386779 Screw Machine Drill Bit 7/32 in Hss Tin

Product Description

The HERTEL 2386779 is a screw machine length drill bit designed for high-speed steel cutting operations requiring a short, rigid tool profile. Built from high-speed steel with a titanium nitride (TiN) coating, it delivers improved surface hardness and extended cutting life compared to uncoated bits. The 135-degree split point reduces walking on entry and lowers thrust force, making it well suited for use in CNC machining centers, drill presses, and production environments. The web-thinned construction further reduces cutting resistance at the tip. At 2.375 inches overall length with a 1.25-inch flute, this bit fits standard screw machine and turret lathe tooling setups.

This drill bit is intended for production drilling in metal fabrication shops, machine shops, and light industrial environments. The straight-cylindrical shank accepts standard drill chucks and collet holders without modification. Its heavy-duty grade rating makes it appropriate for repetitive drilling cycles in ferrous and non-ferrous metals. Machinists, tool and die technicians, and production operators are the typical end users. The short overall length increases rigidity and reduces deflection in close-clearance setups or multi-spindle fixtures.

Key Features

• High-speed steel construction with TiN coating for extended tool life
• 135-degree split point reduces entry walking and lowers drilling thrust
• Web-thinned, parallel web configuration for reduced cutting resistance
• Screw machine length profile increases rigidity in production setups
• Right-hand spiral flute with straight-cylindrical shank for universal chuck compatibility
• Heavy-duty grade rating suited for repetitive production drilling cycles

Compatibility

Designed as an OEM-style replacement or direct substitute for screw machine length drill bits in standard drill chucks and collet holders accepting a straight-cylindrical shank in the 0.2000 to 0.2500 inch decimal inch size range.

Installation Notes

Installation and tool changes should be performed by qualified machinists or tooling technicians with the machine powered down and locked out per applicable lockout/tagout procedures. Confirm chuck or collet size matches the straight-cylindrical shank diameter before securing. Inspect the cutting edges and TiN coating for wear or chipping before each use. Do not exceed the spindle speed rating of the machine or the recommended feed rate for the workpiece material.
