A full line of hand-held bevelers that feature extra-rigid blade locking systems and blades incorporating a radical chipbreaker to transfer heat without cutting fluids has been introduced by Esco Tool. Millhog Right Angle Bevelers feature the EscoLock wedge-style blade lock system which has a large clamping surface and double-threaded screw to hold blades rigidly.
Coupled with cutter blades that incorporate a radical chipbreaker which draws heat away from the tube or pipe surface to prevent workhardening and extend blade life, this system enables bevelers to bevel, face and bore simultaneously without using cutting fluids.
Available for OD beveling, flat facing and ID boring at any angle of prep including “j” preps for orbital welders, cutter blades for Millhog Right Angle Bevelers are offered in TiN coated and Hard Lube versions. The EscoLock blade holder reduces vibration and allows the blade get under the material to pull a thick chip and produce a smooth finish.
Related Glossary Terms
- boring
boring
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
- chipbreaker
chipbreaker
Groove or other tool geometry that breaks chips into small fragments as they come off the workpiece. Designed to prevent chips from becoming so long that they are difficult to control, catch in turning parts and cause safety problems.
- flat ( screw flat)
flat ( screw flat)
Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.
- inner diameter ( ID)
inner diameter ( ID)
Dimension that defines the inside diameter of a cavity or hole. See OD, outer diameter.
- outer diameter ( OD)
outer diameter ( OD)
Dimension that defines the exterior diameter of a cylindrical or round part. See ID, inner diameter.
- titanium nitride ( TiN)
titanium nitride ( TiN)
Added to titanium-carbide tooling to permit machining of hard metals at high speeds. Also used as a tool coating. See coated tools.
- workhardening
workhardening
Tendency of all metals to become harder when they are machined or subjected to other stresses and strains. This trait is particularly pronounced in soft, low-carbon steel or alloys containing nickel and manganese—nonmagnetic stainless steel, high-manganese steel and the superalloys Inconel and Monel.
