Tsubosan Bright-900 Super-D Diamond File K-Type #120 Square 215 mm BDKKA051

[Features] • Sharp cutting and high cutting power. • High-grade diamond grains of uniform shape put more cutting edges in contact with the workpiece. • Resists clogging and is durable. • Because the diamond grains are uniform in shape, the cutting edges protrude evenly from the plating layer even when embedded deeply. This makes the file resistant to clogging and improves grain retention, which means high durability. • Embedding rate: conventional products 50% or less, SUPER-D about 60%. • A distinctive form you can recognize at a glance: the Humanic Curve. • The grip is bent for easy holding. This was originally adopted to improve tooth visibility, but it also makes the file easier to grip and transfers force to the work without waste, improving performance. Bright-900.
