The JMR TN-1000 tubing and pipe notcher is the highest quality and one of the most versatile hole saw notchers on the market. It is manufactured from bar stock, not plate, to increase strength and has a 1.125" induction hardened shaft supported by Timken™ bearings. The custom designed shaft seals prevent bearing and shaft damage and the shaft accepts replaceable hole saw mounting threads.

Angle changes can be made easy due to a Timken™ thrust bearing at the pivot point to increase clamping force while reducing wrench pressure. Use it for prototyping or production work.

These JMR Tube Saws are a true fine-tooth design to notch through round materials. The bodies are heat-treated after they are rolled and welded, giving them a harder tooth and a more true shape. The heat treated body has no coating to flake off onto your tube, so it eliminates paint contamination in your weld area. 

Sizes larger than 2" are available but only for special order.

Features
-More teeth per inch than standard hole saws
- Thicker body than standard hole saws
- No paint/powdercoat to flake off in weld area
- Body threads onto all of our hole saw notchers
