SPECIFICATION: Cutting diameter: 1”~3” Cutting depth: 1” Arbor shank diameter: 10mm Pilot drill bit diameter: 6mm Total length of pilot drill bit: 68mm Package including: 1 x Hole Saw with Pilot Drill Bit 1 x Allen wrench
FEATURES: 1.Adopt High quality tungsten carbide steel. 2. Excellent for making clean and accurate hole on metal sheet. 3. Works better with a electric drill (Excluding in the item). 4.Good performance and long life. 5.Applicable Industry: drill holes on truck frame, lamp post, etc.
INSTRUCTION: Before drilling: 1.Check the hole saw’s condition before use. 2.Install the hole drill bit into the electric drill; and clamp three flats of the shank to the chuck properly. While drilling: 3. Start drilling with a low feed force. 3. Keep the drill at right angles (perpendicular). 5. Increase feed force to medium after positioning the hole. After drilling: 6.After drilling through the metal sheet, keep the drill rotating to exit. 7.When drilling continuously, use cutting fluid to cool the cutting edges. Caution: 8. The rotating speed shall not be too low during drilling, to avoid cutting tool breakage caused by intermittent cutting. 9. Do not use too much force when the pilot drill bit goes through the workpiece, to avoid the cutting edges of the hole drill bit impacting the workpiece.
A must-have valuable cutting tool of metal sheet for you.
