Back spot face tool

A back spot face tool, often referred to as a BF-cutter, is a specialized cutting tool designed for precision machining. It’s primarily used to create a flat, perpendicular surface on the back of a drilled or tapped hole. This process is known as back spot facing.
  • Reduce chip cutting time by at least 80% compared to traditional hand tools
  • Eliminates costly secondary operations and saves time through clever process improvements
  • Standard carbide indexable inserts accommodate a wide range of materials and reduce material costs
  • Tool allows heavy interrupted cuts without excessive chattering
  • Minimum pilot hole diameter Ø10.4mm
  • Unlimited depth-to-diameter ratio with support guides
  • Easy and quick tool change
  • Maximum backbore diameter up to 1.6 times the boring diameter
  • Backspot countersinks with chamfering are available.
  • Use SKD61 material, more shock-resistant, more wear-resistant and more stable.
  • Also easy check our 自動背面锪孔工具

Easy NC Programming

Easy programming by simply offsetting the centers between the machine spindle and hole.

Eccentric grinding process

Under the premise of ensuring rigidity, the use of eccentric grinding process can effectively avoid the empty.

Well designed

Precision crafted, screw off-set design, blades are mounted without gaps for enhanced rigidity. Avoid blade loss caused by vibration, better machining effect.

Eccentric back spot face hole

Solve the processing pain points, processing the back countersunk holes do not need to turn the surface, greatly improving processing efficiency

Rust and corrosion prevention

Electroplating treatment, so that the product is corrosion-resistant, wear-resistant, oxidation-resistant, the blade and the cutter bar close fit, high tightness, comprehensive precision better

Side fastening clamping method

The surface of the toolholder is milled parallel and flat, which makes the clamping force stronger and less slippery during machining.
