⚡ At a Glance
  • Cutting Quality: Clean, precise deburring with controlled material removal
  • Best for: Tradespeople and DIYers needing tidy edge finishing
  • Not ideal for: Tasks requiring an included handle or heavy prying

Cranked countersink blade supplied without handle for deburring metal, plastic and wood. Blades can break if misused, so wear safety goggles and keep away from children.


Access tight or recessed edges - with cranked countersink geometry

Cranked geometry offsets the blade axis so the cutting edge reaches into recesses and around fasteners. The compact 10.4mm diameter concentrates cutting action for localised material removal.

Easier finishing in awkward spots without removing surrounding material. Ideal for chamfering edges near screws or inside small holes.

Versatile deburring across materials - with blade suited to metal, plastic and wood

Blade profile is shaped to scrape burrs cleanly from both hard and soft substrates, allowing consistent edge finishing across different materials. Suitable surfaces listed include metal, plastic and wood.

Reduces the need to swap many specialised cutters during a job. Keeps edge finishing consistent between different workpieces.

Quick integration with existing tools - thanks to blade-only supply

Supplied without handle so the blade can be fitted into compatible countersink holders, arbors or pilot setups chosen by the user. Pack of three gives spare blades ready to fit when needed.

Useful as replacement blades for existing holders or for building a customised set. Having spares minimises downtime on site or in the workshop.
