T41 vs T42 Cutting Discs: Type 1 vs Type 27 Explained

The Shape Difference

T41 (Type 1) is a straight, flat disc — no centre depression. It cuts flush to a surface, ideal for slicing bar stock, pipe and sheet where you need a clean, level cut. T42 (Type 27) has a depressed centre, so the hub sits below the cutting plane; it is built for cutting and light grinding at an angle with a raised-hub guard.

When to Use Which

• Cut pipe / rod / sheet flush → T41.

• Cut and then bevel / grind in one pass → T42.

• For stainless, pick the inox-rated formula (zirconia / alumina, no iron / sulfur / chlorine) to avoid contamination.

Safety Spec to Always Print

Every disc must show Max RPM / peripheral speed (80 m/s), EN12413, and MPA where applicable. A disc run above its rated speed can shatter.
