HM Non-Cutting Drill x30 mm – precision of the four-flute spiral and P.T.F.E. protection

Index: BBH3.080.030.057.00R

Industrial non-cutting drill with tungsten carbide (HM) cutting edges from the BBH3 line, designed for precisely making blind holes on multi-spindle drilling machines, CNC machining centres, and machines using adapters and quick-change holders. The durable steel body is based on a four-flute spiral design, a balanced centring point, two cutting edges Z2, and two negative undercutters V2. This configuration prevents tearing of fibres and guarantees perfectly smooth edges of holes. The working part is protected by a P.T.F.E. coating which reduces resin and dust adhesion, while the steel gripping part with a flat section and adjusting screw facilitates precise mounting in the holder.

Design advantages and technical properties:

• Z2 + V2 cutting system with a four-flute spiral: Four outlet grooves accelerate the removal of material, while the HM edges with V2 undercutters and the centring point ensure a stable drilling process without catching.
• P.T.F.E. protective coating: The P.T.F.E. coating effectively protects the body against resin and contamination buildup, reducing friction and protecting the tool from overheating.
• Steel body and grip with adjusting screw: The cylindrical shank with a flat section facilitates non-slip seating in the adapter, and the integrated adjusting screw allows for precise extension calibration.

Purpose and application range:

The tool is designed for drilling non-through holes in solid wood, wood composites, plastics, and laminated materials.

It is excellent for machining materials such as: solid wood, wood composites, plastics, and laminated boards.
