Dowel drill bit Through hole HM/HW Z2 D8 I35 L70 S10x26 LH

Non-through drill HM 8x35 mm with P.T.F.E. coating – precision machining and high durability 

Index: TBH2.080.030.070.01L

Industrial non-through drill with carbide (HM) cutting edges from the TBH2 line, dedicated to creating precise blind holes on multi-spindle drilling machines, CNC machining centres, and machines equipped with quick change adapters. The design is based on a body made of high-quality steel and utilises a four-flute system, a balanced centring point, two cutting edges Z2, and two negative side cutters V2. This geometry eliminates the risk of edge chipping and guarantees excellent hole finish quality. The working part is protected by a P.T.F.E. coating, which prevents the deposition of resin and carbon build-up, while the steel shank with a flat and set screw ensures stable mounting in the chuck.

Design advantages and technical properties:

• Z2 + V2 cutting system with four flutes: Four chip channels efficiently remove scrap, while the HM edges with V2 side cutters and the centring point guarantee stable tool guidance without tearing.
• P.T.F.E. protective coating: The P.T.F.E. layer effectively reduces resin and dust adherence, lowering friction and protecting the tool from overheating.
• Steel body and shank with set screw: The cylindrical shank with a flat ensures secure mounting in the adapter, while the built-in adjustment screw allows for precise extension calibration.

Intended use and application range:

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

It works excellently in machining materials such as: solid wood, wood composites, plastics, and laminated boards.
