CNC Spindle Tension Meter – CAT40 / BT40 Spindle Clamping Force Tester
Product Overview
This spindle tension meter is a precision testing instrument designed to measure the clamping force (drawbar force) of CNC machine spindles with CAT40 and BT40 tapers. Also known as a spindle detection gauge or handle spindle testing instrument, it allows operators and maintenance technicians to quickly verify that the spindle drawbar is providing the correct gripping force on tool holders.
Maintaining proper spindle tension is critical for machining accuracy, tool life, and safety. Insufficient clamping force can cause tool pull-out, chatter, poor surface finish, and even spindle damage. This instrument provides a simple, reliable way to check spindle health during routine maintenance, after a crash, or before a high-precision job.
Key Features
Dual Compatibility – Works with both CAT40 and BT40 spindle tapers (please specify when ordering).
Accurate Force Measurement – Provides a clear, repeatable reading of the spindle’s clamping force.
Handle-Type Design – Easy to insert, position, and remove from the spindle taper.
Mechanical or Digital Readout – Available in dial gauge or digital display options for easy reading.
Rugged Construction – Built from hardened steel and durable components for long service life in shop environments.
Simple Operation – Insert into the spindle, activate the drawbar, and read the force value.
Portable & Lightweight – Can be used across multiple machines in the shop.
No Power Required – Mechanical models need no batteries or external power; digital models use standard batteries.
Calibration Ready – Designed for periodic calibration to maintain accuracy.

Why Choose This Instrument?
Prevent Costly Downtime – Detect low clamping force before it causes tool pull-out or scrap.
Improve Machining Quality – Ensure consistent tool holding for better surface finishes and tolerances.
Extend Tool Life – Proper clamping reduces vibration and premature tool wear.
Easy to Use – No special training required; insert, activate, and read.
Built for the Shop Floor – Durable construction stands up to everyday use.
Versatile – One tool can be used across multiple CAT40 or BT40 machines.
Note
Please confirm your spindle taper type (CAT40 or BT40) and desired display type (dial or digital) before ordering. Measurement range and accuracy vary by model. This instrument is a maintenance and inspection tool, not a production cutting tool. Regular calibration is recommended for continued accuracy.
