PCD Hinge Boring Bit

PCD hinge boring bit for row drills, bench drills and CNC drilling setups. 10 mm D-flat shank for multi-spindle boring machines, 12.7 mm shank for CNC machining centres.

Design and Construction

The PCD hinge boring bit drills hinge cups and hardware holes with a diamond cutting edge. The chart lists two shank options: a 10 mm D-flat shank for multi-spindle boring machines or bench drilling machines, and a 12.7 mm (1/2-inch) shank for CNC machining centres; the cutting material is PCD as listed.

How It Works

The bit drills the hinge bore in a single drilling cycle: the diamond cutting edges shear the hole wall while the listed shank matches the machine chuck. PCD holds the cutting edge across abrasive panel materials over extended drilling runs.

Applications

  • Hinge cup boring
  • Hardware hole drilling
  • Multi-spindle boring machines
  • CNC drilling centres (12.7 mm shank)

Suitable Materials

  • Melamine-faced particleboard
  • MDF and laminated boards
  • Plywood panels
  • Selected abrasive panel materials

Suitable materials strip

Material Comparison: Tungsten Carbide vs. PCD (Diamond)

This tool is a PCD (polycrystalline diamond) cutter. Tungsten carbide is the conventional alternative. Typical industry data:

Property Tungsten Carbide Cutter PCD (Diamond) Cutter (This Tool)
Hardness 1,500-2,000 HV 7,000-9,000 HV
Best suited for General profiling across mixed materials Highly abrasive boards and long production runs
Tool life vs. carbide baseline 1x (baseline) 10-15x on abrasive panels (typical industry data)
Edge wear on MDF/particleboard Wear visible within shorter runs Minimal wear over extended runs
Toughness Higher toughness; tolerates impacts better Lower toughness; sensitive to impact and metal contamination
Regrinding Can be reground Not reground in the normal case
Initial cost Lower Higher
Cost per part at long runs Usually higher Usually lower on abrasive, long-run work
Typical choice Short runs and mixed materials This tool: long-run profiling on abrasive boards

Typical industry data; actual tool life varies with workpiece, machine and feeds.

Frequently Asked Questions

Which shank options are listed?

+The chart lists a 10 mm D-flat shank for multi-spindle boring or bench drilling machines and a 12.7 mm (1/2-inch) shank for CNC machining centres.

What is this bit used for?

+Hinge cup and hardware hole boring on panel materials.

Why choose PCD for hinge boring?

+Panel boards are abrasive; the diamond edge holds its cutting geometry far longer than carbide over long drilling runs.

What should I provide before ordering?

+Confirm the shank option against your machine chuck, plus the required bore diameter and panel material.
