MAXIMIZE LIFE OF YOUR ANNULAR CUTTER / PREVENT PREMATURE DULLING OF BLADES
Use our HSS annular cutters to cut suitable materials only
Recommended for steel sections and steel plate. Can also be used for the materials listed below.
For hardened metals, use carbide annular cutters, also available in our store.
Secure workpiece and drill properly
There should be no movement between the workpiece and drill during cutting.
If using a magnetic drill, check there are no metal chips on the magnet base before each cut. They will prevent full magnetic adhesion with the workpiece.
If the workpiece is less than 1/2” thick, use a 3/8” steel sheet under it to ensure the magnetic drill will grip it firmly.
Match the annular cutter size and material drilled to the correct feed rate
Recommended speed at which holes should be cut in mm/min = *Feed rate F x *Rotation Speed R
As an illustration, using an annular cutter size ½” to drill holes in low carbon steel, the speed at which the hole is cut should be between 0.08 x 612 = 49 mm/min and 0.13 x 612 = 80 mm/min. Adjust the rotation speed of the feed handle to match the recommended speed.

No complaints - used with battery & elec. mag drills to slug holes in W columns and beams for conduit penetrations & misc. attachments. these make for quick clean and accurate job. did not really need the smaller cutters; but for the cost, getting kit vs. single cutters was easy decision. they have kept good edge with correct speed and lubrication & find myself using them more in mag drill and less in drill press

I used these cutters replacing frame rails on a t800 dump truck . Drilling 5/16 double frame so 5/8 thick . Using a dewalt drill with oiler . I've drilled 40 plus holes. Still cutting like new

These bit arrived very quickly and were exactly as described except for they work better and last longer than similar more expensive brand bits. Great product and cost will have me ordering more of them in different sizes!

I used these bits to drill a couple dozen holes in a very thick Peterbilt frame. I used 3 of the bits but mostly the 11/16". It cut great and never seemed to loose it's edge even after cutting 20+ holes. Well worth the money
