Techniks 22925-1.75F End Mill Holder CAT40 1 Inch Bore

Product Description

The TECHNIKS 22925-1.75F is a CAT40 taper shank end mill holder designed for CNC machining centers that use the CAT40 spindle interface. It accepts a 1-inch bore and provides a 1.75-inch projection from the gauge line to the nose face, keeping tool overhang predictable and consistent. The nose diameter measures 2 inches. Through-coolant capability routes cutting fluid directly through the holder to the tool tip, supporting higher cutting speeds and extended tool life in demanding applications. Machinists and tool crib personnel rely on this holder for rigid, repeatable tool clamping in production environments.

This holder is suited for vertical and horizontal machining centers running CAT40 tooling. It is a standard choice for end milling operations where through-coolant delivery is required, such as deep-pocket milling, high-feed milling, and operations in difficult-to-machine materials where heat management is critical. The 1-inch bore accommodates standard 1-inch shank end mills. With an overall length of 4.437 inches, the holder fits within typical tool-length offsets on most CAT40-equipped machines.

Key Features

• CAT40 taper shank for direct spindle mounting on CAT40-equipped machining centers
• 1-inch bore diameter for secure clamping of 1-inch shank end mills
• 1.75-inch projection for controlled tool reach and reduced overhang
• 2-inch nose diameter for robust holder rigidity
• Through-coolant design delivers cutting fluid directly to the tool tip
• Overall length of 4.437 inches for consistent tool-length offset setup

Compatibility

Designed as an OEM-style end mill holder for CNC machining centers equipped with a CAT40 spindle interface and accepting 1-inch shank end mills.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with CAT40 tooling standards. Power down and lock out the machine spindle before loading or unloading the holder. Use a calibrated torque wrench and the appropriate retention knob when securing the holder in the spindle, following the machine tool manufacturer's specified pull-stud and drawbar requirements. Inspect the taper and bore for chips or damage before each use to maintain runout accuracy.
