• cutter

During drilling work on high floors, there is a possibility that debris may fall down. Round, sharp debris can be very dangerous if it falls and hits someone. Additionally, if debris falls inside the pipe during drilling, it is very difficult to retrieve. Therefore, if you attach this stopper-equipped center drill to the hole cutter for drilling work, it will be safe and secure.

• cutter

A specialist for opening single diameters faster, more, and smoother. The main material is HSCO steel (cobalt high-speed steel), which excels in wear resistance and heat resistance. It is coated with titanium to prevent the welding of chips due to heat, extending the life of the blade.

• drill
• cutter

With one tool, you can drill various sizes of holes. The main body is made of HSCO steel (cobalt high-speed steel), which offers excellent wear resistance and heat resistance. It is coated with titanium to prevent chip welding due to heat, extending the life of the blade.

Thanks to the bimetallic multiple shell blades, stable and safe drilling without snagging is possible. The blade diameters (117, 143, 168, 217) are precise dimensions that allow for accurate hole drilling.

• drill
• cutter

After hardening, a uniform cutting edge height allows for high cutting performance. By replacing the center drill with a four-flute drill, it becomes a hole cutter for vinyl. Chips can also be easily removed.

Safety blade shape with no snagging (squareness angle 6 degrees) Finish close to a true circle with minimal burrs (inclination 4 degrees)

• drill
• cutter

It uses a durable thin-blade bi-metal design. It reduces heat generated by resistance during drilling, allowing for precise hole drilling. With a one-touch attachment and detachment system, it can be used with a single shank for all sizes (53φ to 130φ), making it very economical.
