Driving precision in Indian automotive manufacturing
The Indian automotive sector — one of the world's largest — demands uncompromising tool life, dimensional consistency, and high-volume throughput. Sumitomo's automotive-grade tooling is trusted by OEMs and Tier-1 suppliers for engine, transmission, chassis, and EV component machining.
Key applications
- Cylinder bore turning & finishing
- Crankshaft & camshaft turning
- Gear hobbing & shaping
- Hardened steel finishing (HRC 45–65)
- Aluminium alloy milling (EV trays)
- Cast iron drilling & boring
Recommended tooling
SUMIBORON BNC Series
CBN for hardened steel finishing — brake discs, bearing housings
SUMIDIA PCD
Diamond tooling for aluminium engine blocks and EV housings
WC Carbide — AC/AH Series
General turning & milling of cast iron and steel components
Certified precision for flight-critical components
Aerospace manufacturing demands tools capable of machining titanium alloys, nickel superalloys (Inconel, Waspaloy), and CFRP composites — materials that are notoriously difficult to cut. Sumitomo's specialist grades deliver controlled tool wear, surface integrity, and traceability for AS9100 and NADCAP environments.
Key applications
- Titanium structural turning & milling
- Nickel alloy blade / disk machining
- CFRP panel trimming & drilling
- Stainless steel airframe parts
- Landing gear component turning
- Engine casing boring
Recommended tooling
ACE Series (Ti Grades)
Dedicated carbide grades with specialised geometry for Ti-6Al-4V
SUMIBORON BX Series
High-speed CBN turning of heat-resistant superalloys
SUMIDIA DCN / DCA
PCD routing and drilling for CFRP and GFRP composites

Key applications
- External turning and profiling
- Grooving, cut-off and back turning
- External and internal threading
- Very small diameter boring from ø1.0 mm
- Internal grooving
- Two operations from one holder (twin head)
Recommended tooling
SUMIBORON (CBN) Small Hole Boring Bars
BXBR and BNBX series for very small bores in hardened steel
SUMIDIA (PCD) Small Hole Boring Bars
DABB type for small bores in non-ferrous metals
Twin Head Holder — CKBE / CKBB type
One holder for I.D. + O.D. or I.D. + I.D. operations
