Hinge boring bit HM Z2+V2 D35 L70 S10x26 LH

HM Cored Drill Bit 35 mm with P.T.F.E. Coating – precision machining and high durability

Index: HBH2.350.070.1L

Industrial cored drill bit with sintered carbide (HM) cutting edges from the HBH2 line, designed for precision drilling of holes for cored hinges on multi-spindle drilling machines, CNC machining centres, and machines equipped with quick-change adapters. The design, based on a high-quality steel body, features a balanced centering tip, two cutting edges Z2, and two negative undercutters V2. This geometry eliminates the risk of chipping edges and guarantees a perfectly smooth bottom of the hole. The working part is protected by a P.T.F.E. coating that prevents resin and soot buildup, while the steel shank with a flat section and adjustment screw ensures stable mounting in the chuck.

Structural advantages and technical properties:

• Z2 + V2 cutting system with centering tip: Two HM cutting edges with V2 undercutters and a centering tip guarantee stable guidance, precise positioning, and clean drilling without tear-out.
• P.T.F.E. protective coating: The P.T.F.E. layer on the working part effectively limits the adhesion of resin and dust, reducing friction and protecting the tool from overheating.
• Steel body and shank with adjustment screw: The cylindrical gripping section with a flat portion ensures a secure fit in the adapter, while the built-in adjustment screw allows for precise calibration of the extension.

Purpose and range of application:

The tool is intended for drilling holes for cored hinges and fittings in solid wood, wood composites, and laminated materials.

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