Mitutoyo 985-146 T-handle Tap Wrench 13 Inches

Product Description

The MITUTOYO 985-146 is a T-handle tap wrench designed for hand-tapping operations in metal, plastic, and other materials. It provides the mechanic or machinist with direct rotational control when driving taps by hand, reducing the risk of tap breakage compared to powered methods. The fixed T-handle style delivers balanced two-handed torque application across the full 13-inch overall length. At 0.5 pounds, the tool is lightweight enough for extended use on a bench or at a machine. No ratcheting mechanism is included, keeping the design simple and direct-drive for applications where feel and control matter most.

This tap wrench suits machine shops, maintenance facilities, and fabrication environments where hand-tapping is performed on a regular basis. It is appropriate for threading operations on workpieces that are already fixtured or clamped, and it works alongside standard tap sets across a range of thread sizes. The 13-inch length gives sufficient leverage for moderate-sized taps without becoming unwieldy in tight spaces. Machinists, tool-and-die workers, and maintenance technicians are the primary users of this style of wrench.

Key Features

• T-handle style provides balanced two-handed grip for controlled torque during hand tapping
• Fixed, non-ratcheting drive for direct feel and positive control over tap rotation
• 13-inch overall length delivers adequate leverage for a broad range of tap sizes
• Lightweight at 0.5 pounds, reducing hand fatigue during extended use
• Simple construction minimizes maintenance and points of failure

Compatibility

Designed as an OEM-style hand tool compatible with standard tap shank sizes commonly used in general machining and maintenance tapping operations. Verify chuck capacity against the tap shank diameter before use.

Installation Notes

No power source or lockout procedure is required for hand tap wrench use, but ensure the workpiece is securely clamped before beginning tapping operations. Apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread quality. Insert the tap squarely into the tap wrench chuck and tighten the chuck before applying torque. Periodically back off one-quarter turn during tapping to break chips and reduce the risk of tap breakage.
