Brochas y Bruñidores

Size, true and finish with precision. This collection brings together tapered cutting broaches for opening and fitting holes, smoothing broaches for polishing bores, and a full range of burnishers—from mirror-finished steel to non-marring agate—for tightening prongs, closing bezels and refining channels.

What you’ll find here

  • Cutting broaches — tapered round, square, triangular & pivot styles for enlarging and truing holes in hinges, tubing and settings.
  • Smoothing broaches — highly polished tapers to burnish/finish bores after cutting.
  • Burnishers — straight, curved, oval/knife and prong-burnisher profiles in steel or agate for closing metal and producing a bright finish.
  • Sets & singles — student to pro assortments with holders, plus replacement singles in popular tapers and profiles.
  • Accessories — handles, holders and lubricants for smoother cutting/burnishing.

How to choose

  • Task: Use cutting broaches to incrementally open/true; follow with a smoothing broach to polish. Choose steel burnishers for shaping/closing; agate when you need a mirror finish with minimal marking.
  • Shape: Round for general bores; square/triangular to “find” corners or quickly remove material; pivot for watch stems and small precision work.
  • Profile (burnishers): Straight for flats/edges, curved for bezels and channels, knife/oval for tight access and prong shoulders.
  • Handling: Add a comfortable handle or pin-vise for better control on small tapers.

Technique & care

  • Broaches cut on a gentle, twisting forward motion—don’t force or reverse under load.
  • Use a light lubricant; clear chips often. Finish with a smoothing broach for a bright, accurate bore.
  • Keep steel burnishers mirror-polished (strop on leather) so they move metal cleanly without scratching.
