HSS corner rounding cutter R2 mm — technical specifications
Concave form cutter NFRk DIN 6518 — dimensions, material and tool specifications
Concave corner rounding cutter R2 mm type NFRk from Varel is a form cutter conforming to the standard DIN 6518, designed for precision milling of quarter-round profiles. Made of high-speed steel (HSS) HSS (High Speed Steel, hardness 64 HRC) with 4 cutting edges that ensure even distribution of cutting forces. The Weldon straight shank Ø10 mm ensures rigid, secure clamping in a collet chuck.

Applications of the R2 mm corner rounding cutter
Workpiece materials and compatibility by ISO material group
The R2 mm HSS concave quarter-round radius cutter is a versatile form cutter used to machine rounded workpiece edges with a radius of R2 mm. It is particularly suitable for injection mold and stamping die manufacturing, where repeatable rounded profiles are required. The NFRk cutter operates perpendicular to the machined edge — the concave tool profile produces a convex quarter-round profile on the workpiece.

Machining tip
For profile milling with a corner rounding cutter, use down milling (climb milling) for a better surface finish. For soft materials (Al, Cu), use higher cutting speeds and lower feed per tooth to avoid built-up edge (BUE).

Frequently asked questions
The R2 mm HSS quarter-round cutter to DIN 6518 effectively machines structural and alloy steels (groups 1.1–1.8), stainless steels (2.1–2.3), gray and ductile cast iron (3.1–3.5), copper and brass (6.1–6.4), aluminum (7.1–7.4) and plastics (8.1–8.3). It is not recommended for hardened steels above 45 HRC.
The concave radius cutter (type NFRk) forms a convex rounded edge on the workpiece — in this case, a quarter-round profile with a radius of R2 mm. The convex radius cutter (type NFRx), in turn, produces a concave recess in the material. Both types are covered by DIN 6518.
For a cutter with a Ø10 mm Weldon shank, the optimal solution is a collet chuck ER32 (clamping range 2–20 mm) with an ER collet matching the shank diameter. ER collet chucks provide concentric clamping with radial runout below 0.01 mm, resulting in a better surface finish during profile milling. The ER collet distributes clamping force evenly around the entire shank circumference, eliminating the risk of tool deformation.
