DESCRIPTION
Product description:
1.Set both cutting blades on holder tightly and correctly.
2.To adjust the size, locate the inner edges of the blade holders against the size graduation. For example number "40" for a 1 (40 mm) diameter hole.
3.Set the two blade holders at the desired graduation on the measure bar by tightly screwing the hexnuts using an L-shape hex wrench. 4.Use the chisel end drill to bore thin wood. Use the twist drill for thick wood.
5.Before boring, hold the two sides of veneer or timber firmly by stepping on it. Take care to set the twist drill or chisel end drill atthe center of the desired hole, then start boring. When using a power drill, be sure to contact the cutting blades gradually and slowly on the object to be bored. Abrupt contact of the blades on the boring object can give shock to your hands.
6.If you wish to do deep boring (1" to 2", or 25mm to 50mm), use the "free doughnut" from one side of the timber, then start boring again from the other side until the cutting blades bore through a hole making a doughnut-shaped disc.
7.A large hole with maximum diameter of 5"(120mm) can be bored by using the measure bar.
Notice: please don't use on steel sheet or other metal.
Package include:
1 pcs adjustable circle hole saw cutter brill bit.
