Why this Milwaukee tap stands out

Durability meets precision with a high carbon steel body paired with a hard-wearing black oxide finish. The straight plug design provides straightforward alignment for internal threading, helping you produce accurate, repeatable threads in metal parts, brackets, housings, and more. The compact 3.25" length makes it easy to maneuver in tight workspaces, while the clamshell packaging ensures safe transport and display in retail or shop environments.

Ideal uses

• Cutting internal M11-1.5 metric threads in steel, cast iron, and other metal substrates
• Repairing damaged threads inside housings, brackets, engine components, and machinery
• Creating new threaded holes in fabrication projects and custom parts
• Maintenance and repair shops, mechanical rooms, and fabrication shops

How to use

1. Prepare the workpiece and drill a pilot hole sized appropriately for the M11-1.5 thread (pilot size determined by standard threading guidelines).
2. Secure the part in a vise or with a tap guide to prevent movement during tapping.
3. Apply a light coating of cutting fluid to the tap to reduce friction and heat buildup.
4. Place the plug tap in a tap wrench or T-handle and begin turning clockwise, keeping the tap square to the surface.
5. Advance smoothly until you reach the required depth, then back off slightly to break and clear chips.
6. Inspect the finished threads and deburr the hole if needed before assembly.

Care & maintenance

After use, clean away chips and wipe the tap dry to prevent corrosion. Store in its protective clamshell packaging or a dedicated tap holder to avoid nicks and bending. For best longevity, use with appropriate cutting fluid and avoid excessive torque that could dull or deform the tool.
