5PCS Professional Drill Bit Woodworking Hole Saw Wood Cutter Tool (15mm/18mm/20mm/22mm/24mm)

Applicable method: 1.The wood must be fixed and cannot be moved. It should be at a right angle of 90 degrees to the opening. When positioning the drill, please wait a moment and then drill slowly. During operation, if abnormal chip removal is not ideal, please stop working, exit the hole opener, and clean the cutter head and inner hole before you can work again. 2.When using the hole opener, please be sure to master it properly. Select the tachometer to smoothly enter and exit to prevent the blade from cracking. If the drill is used, the switch should be controlled during operation to reduce the speed as much as possible. 3.When using, take protective measures to prevent wood chips from splashing and hurting your eyes.
