  • This Veritas Lapped 25° blade, 2-1/4" wide by 3/16" (0.187") thick, is for the Veritas Bevel Up Low Angle jack Plane, made from PM-V11 tool steel

Veritas Lapped Plane Blades

  • Lapping the blade is the critical first step when preparing a blade for use
  • The reason for this may not be obvious until you understand that the sharpness of a cutting edge is determined by the intersection of two surfaces (the bevel and the opposing face), and that the smoother and flatter these two surfaces are, the keener the intersection
  • The lapping process can be an arduous task, especially when dealing with today's hard tool steels
  • This process, when done by hand, involves numerous steps and will require a good deal of your time to achieve an acceptable working surface
  • To reduce the time and effort you spend on this activity, Veritas now laps their PM-V11 plane blades on the face (non-bevel side) to a flatness tolerance of ±0.0002" or better over the working surface, and with an average roughness surface finish of 5 micro-inches (0.000005") or better
  • Because you begin with a blade that has already been lapped flat, your efforts may now be focused on providing the final polish to the face and honing the micro-bevel – tasks that require significantly less time and effort than lapping the blade face
  • On Veritas regular and bevel-up plane blades, the working surface is the section of the face that extends from about 1/8" below the bottom of the screw slot to the cutting edge; on shoulder and bullnose plane blades, it is the widest section of the face from the shoulder to the cutting edge
  • Average roughness (Ra) measures the height variations in the surface over a given area and then provides an average roughness value to represent the surface finish – the lower the value, the better the finish
  • Lapped 38° and 50° blades are also available for the Veritas Low Angle Jack Plane, as well as a toothed A2 blade for working difficult grain
