Parlec C40-25BB8 Rotary Tool Holder Blank CAT40 2.5in

Product Description

The PARLEC C40-25BB8 is a rotary tool holder blank with a CAT40 taper shank, designed for use on CNC machining centers and vertical or horizontal mills. The blank format means the bore is unfinished, allowing the end user or toolroom to custom-bore the nose to a specific diameter or fit. Key dimensions include a 2.5-inch blank diameter, a 10.69-inch overall length (OAL), and a projection from flange to nose end of 7.25 inches. Weighing 10 pounds, this is a substantial holder suited for heavy-duty toolroom work. Installation and final machining are performed by qualified machinists or toolroom technicians.

This holder blank is intended for use in toolrooms and production machining environments where standard off-the-shelf holders do not meet a custom bore requirement. The CAT40 taper shank interfaces directly with CAT40 spindle receivers common on full-size vertical machining centers and horizontal machining centers. It is appropriate for both high-volume production shops and job shops that need custom tooling solutions. The 8.0-inch projection from gage line to nose end supports applications requiring extended reach or specific gage-line clearance.

Key Features

• CAT40 taper shank for direct spindle interface on compatible machining centers
• 2.5-inch blank diameter provides substantial material stock for custom boring operations
10.69-inch overall length with 7.25-inch flange-to-nose projection for extended reach applications
• 8.0-inch projection from gage line to nose end suits applications requiring precise gage-line positioning
• Solid construction at 10 pounds supports heavy-duty toolroom machining
• Unfinished bore allows custom toolroom modification to exact fit requirements

Compatibility

Designed as an OEM-style toolroom blank compatible with CAT40 spindle interfaces on standard CNC vertical and horizontal machining centers.

Installation Notes

Final boring of the blank nose should be performed by a qualified machinist using appropriate lathe or boring equipment before mounting in the spindle. Ensure the machining center spindle is fully de-energized and the tool changer is disabled before installing or removing tool holders. Follow the machine tool manufacturer torque specifications for drawbar retention. Inspect the CAT40 taper and spindle taper for contamination or wear before seating the holder.
