คุณลักษณะ

• Uses a 3-blade set that is hard to tip even for hard use.
• Drilling of thick steel plates and perforating curved surfaces such as thick metal pipes are also possible.
• The blade design is designed to reduce friction, resulting in lighter and speedier drilling and longer life than conventional (flat) blades.
• Use of a step center drill reduces the impact when the center drill is penetrated.
• Work Material: Iron Plate, Thick Steel Plate (25 mm or Less), Stainless Steel Plate (10 mm or Less), Aluminum Plate (5 mm or Less), Pipe Material, etc.
• * In order to cause chip chipping, do not hit the carbide cutting edge against hard objects or strongly touch the work material when penetrating the center drill.
