Through-hole drill HM 7x43 mm – precision engineering and P.T.F.E protection
Index: BBH4.070.043.070.00L
Industrial through-hole drill with carbide-tipped (HM) blades from the BBH4 line, designed for accurately creating blind holes on multi-spindle drilling machines, CNC machining centres, and machines using quick-change adapters and chucks. The durable steel body is based on a design with four flutes, a balanced centring tip, two cutting edges Z2, and two negative undercuts V2. This arrangement prevents fiber tearing and guarantees perfectly smooth hole edges. The working part is protected by a P.T.F.E. coating that reduces resin and dust adhesion, while the steel gripping part with a flat section and adjustment screw facilitates precise mounting in the holder.
Construction advantages and technical properties:
- Z2 + V2 cutting system with four flutes: Four outlet grooves accelerate chip removal, while the HM edges with V2 undercuts and the centring tip ensure stable drilling without tearing.
- P.T.F.E. protective coating: The P.T.F.E. coating effectively protects the body from resin and debris build-up, reducing friction and protecting the tool from overheating.
- Steel body and grip with adjustment screw: The cylindrical shank with a flat section facilitates slip-free seating in the adapter, and the integrated adjustment screw allows for precise calibration of the extension.
Purpose and range of application:
The tool is intended for drilling operations creating blind holes in solid wood, wooden composites, plastics, and laminated materials.
It performs excellently in the processing of materials such as: solid wood, wood composites, plastics, and laminated boards.
