Product Description
The CMT 991.083.00 Hex Key - 3 x 90 x 135mm is a T-shaped hex key designed for use with CMT router bits, cutter heads, and related accessories. With a 3mm hex drive and a T-handle configuration measuring 90 x 135mm, this wrench delivers the leverage and control needed to securely tighten or remove fasteners on precision woodworking tooling - giving operators confident, fatigue-reducing grip compared to a standard L-shape hex key.
Key Features
- T-shaped hex key design - the cross-handle configuration provides two-handed leverage and better torque control, reducing strain when tightening fasteners on router bits and cutter heads
- 3mm hex drive size - matches the fastener specification common to CMT tooling, ensuring a precise, slip-free fit that protects both the fastener and the tool
- 90 x 135mm handle dimensions - the extended handle geometry gives the user a firm, comfortable grip and increased mechanical advantage without the need for additional tools
- Purpose-built for CMT tooling - engineered to work seamlessly with CMT router bits, cutter heads, and accessories, helping maintain proper assembly integrity and performance
Why This Product
- The T-handle format means more control and torque with less effort - a practical advantage when adjusting router bits or cutter heads repeatedly during a workshop session
- The exact 3mm hex sizing ensures a snug, accurate engagement with CMT fasteners, reducing the risk of rounding out hardware on precision tooling
- Compact enough to store with a CMT router bit set while still offering the handle length needed for confident tightening - a balance of portability and usability
- Sold individually, making it a straightforward replacement or addition when a dedicated hex key for CMT accessories is needed at the workstation

Frequently Asked Questions
What is the difference between a T-shaped hex key and a standard L-shaped hex key?
A T-shaped hex key features a cross-handle that allows the user to grip with the full hand and apply torque from both sides of the handle. This provides greater mechanical advantage and more comfortable, controlled tightening compared to the single-arm grip of a standard L-shape hex key.
What size fasteners does this hex key fit?
This hex key has a 3mm hex drive, designed to engage 3mm hex socket fasteners as found on compatible CMT router bits, cutter heads, and accessories.
Can this hex key be used with non-CMT tooling?
While this hex key is engineered as a companion tool for CMT router bits, cutter heads, and accessories, the 3mm hex drive is a standard size. Its suitability for use with other brands depends on whether those products use 3mm hex fasteners.
How many hex keys are included per order?
This product is sold individually - one CMT 991.083.00 T-shaped hex key per unit.
