Why ASI parts last
Results first: what we measure on every chisel, then how we make it.
- In-house heat treatmentCarburising, induction hardening, tempering and segment tempering
- Zone hardness 55 / 50 / 45 HRCTip, middle, head on ASI 42CrMo4
- Serial and heat numberMarked on every chisel
- Making parts in AmbalaSince 2012
Hardness by zone
- Headabout 45 HRCTakes the piston blow without cracking
- Middleabout 50 HRCTough body that resists bending
- Tipabout 55 HRCHard working end that resists wear
Every chisel is traceable
- Dot-pin serial and model number
- Heat number of the steel

How an ASI chisel is made
Six steps from bar to dispatch. We show what is done and measured, not settings.
-
[placeholder: photo, bar cutting]
Bar cutting

Machining
Turning on CNC turning centres; drilling, milling and grinding.
-
Heat treatment
Hardening, carburising and induction hardening in our own plant.
-
Tempering and segment tempering
Zone tempering gives each part of the chisel its own hardness.
-
