Manual Hand Shear Manufacturer,Supplier and Exporter in India

Product Code : EL-SWES-8748
Jlab Export is a leading Manual Hand Shear Manufacturer,and suppliers in India

A manual hand shear cuts steel flat bar and round rod by hand, with no saw cut, no swarf and no power supply. This one has a 12 in blade of hardened high carbon steel set in a heavy duty steel frame. It cuts flat steel up to 2-3/4 x 1/4 in (70 x 6 mm) and round rod up to 1/2 in (13 mm). The thickest stock it takes is 1/4 in (6 mm).

Workshop Practice: Cutting Weld Practice Pieces

In a welding or fitting workshop, trainees mark flat bar to length with a Scriber and an Engineers Square, then cut it on the shear. The square-cut pieces become the plates for butt, lap and fillet joints run on the Shielded Metal Arc Welding Machine.

A sheared edge has a slight roll on one face and a small burr on the other. Students take the burr off with a Flat File before fit-up. Teachers can set the same cut on the shear and on a Hacksaw Frame. The class then compares the time taken, the edge left and the metal lost to the saw.

Frequently Asked Questions

What is the biggest bar this hand shear will cut?
Flat steel up to 2-3/4 x 1/4 in (70 x 6 mm) and round steel rod up to 1/2 in (13 mm). No piece should be thicker than 1/4 in (6 mm). Heavier sections belong on a power saw.

Can I cut harder steel by putting more force on the handle?
No. Keep to the capacities above. Hardened steel, spring steel and tool steel can chip a hardened blade. A pipe slipped over the handle for extra pull loads the frame and pivot far beyond normal hand force.

How do I get a clean, square cut?
Fix the shear firmly to a bench or stand first. Lay the bar flat on the lower blade and at right angles to it, with the scribed line set on the edge of the lower blade. Cut deep in the jaws, close to the pivot, where the force is greatest, in one steady stroke.

How should the blades be looked after?
Brush scale and chips off the blades after each class and put a few drops of oil on the pivot. Never cut wire rope, nails or hardened parts. A blunt or chipped blade leaves a ragged, burred edge and needs regrinding before further use.

When should I use the shear instead of snips or a hacksaw?
Use the shear for straight cuts across flat bar and rod. Tin snips suit thin sheet and curves. A hacksaw is the better choice for tube, angle and other hollow or open sections, which a flat blade would crush.
