Key features

BM-7 – Compact radius edge beveler
Quick, simple to use beveller that creates a perfect radius (R2, R3, R4 or R5) in just one pass, saving time and money over conventional grinding methods.
Superior features of BM-7 include:

  • lightweight and compact design
  • ideal for radius edge beveling
  • small overall dimensions
  • excellent for limited access
  • continuous bevel width adjustments
  • one single 45 degrees milling head for both radius and V bevels

Beveling with radius R2, R3, R4, R5
Creating a perfect radius on material edges prior to painting has crucial implications on lifetime of material cover.

BM-7 creates a perfect radius on both straight…

…and curved edges.

Beveling up to 7 mm

Pipe beveling

Countersinking down to ca 35 mm (1.38’’)

Solution for rounding edges on steel elements

Radius prevents rust from building up on sharp edges.
The current EN 1090 & EN-ISO 12944 Part 2 applications directive demands a soft or radius edge applying to all steel sections before painting, to prevent rust build up on sharp edges.

Without a radius

Flaking and rust

With a radius

Perfect finish
