HM Non-through Drill 5x27 mm with P.T.F.E. Coating – precision machining and high durability 

Index: TBH1.050.027.057.01L

Industrial non-through drill with cemented carbide (HM) cutting edges from the TBH1 line, designed for creating precise blind holes on multi-spindle drills, CNC machining centres, and machines equipped with quick-change adapters. The design is based on a high-quality steel body that uses a configuration with four spirals, a balanced centring point, two cutting edges Z2, and two negative undercutters V2. This geometry eliminates the risk of edge chipping and guarantees excellent hole finishing quality. The working part is protected with a P.T.F.E. coating, which prevents resin and soot build-up, and the steel shank with a flat section and adjusting screw ensures stable mounting in the holder.

Design Advantages and Technical Properties:

• Z2 + V2 Cutting System with Four Spirals: Four flutes efficiently remove chips, while the HM edges with V2 undercutters and the centring point ensure stable tool guiding without jerking.
• P.T.F.E. Protective Coating: The P.T.F.E. layer effectively reduces resin and dust sticking, lowering friction and protecting the tool from overheating.
• Steel Body and Shank with Adjusting Screw: The cylindrical gripping part with a flat section guarantees a secure fit in the adapter, while the built-in adjusting screw allows for precise calibration of the reach.

Intended Use and Application Range:

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

It performs excellently in processing materials such as solid wood, wood composites, plastics, and laminated boards.
