4.5″*9/32″*7/8’’inch 115*7.0mm Carbon Steel Grinding Disc
Product Overview
The 115*7.0mm Carbon Steel Grinding Disc is engineered for high-efficiency material removal on low-to-medium carbon steel. Utilizing zirconia-alumina abrasives with ceramic-reinforced resin bonding, this disc delivers 30% faster stock removal than conventional wheels while minimizing heat generation. Manufactured under ISO 9001-certified processes, it features iron-optimized grit geometry to prevent “cold brittleness in carbon steel. Its 7mm thickness balances cutting depth and stability, ideal for automotive repair shops and metal fabrication plants requiring precision on ASTM A36/AISI 1045 materials.
Product Advantages
1.Heat-Controlled Grinding: Proprietary cooling channels reduce workpiece temperature by 40%, preventing surface hardening and micro-cracks.
2.Anti-Loading Design: structure with 15% porosity resists metal particle clogging during continuous operation.
3.Multi-Speed Compatibility: Stable performance at 8,500-13,300 RPM, suited for angle grinders from Bosch to Makita.
Applications
1.Automotive Frame Repair: Removes weld seams on chassis components without compromising structural integrity.
2.Tool Maintenance: Sharpens carbon steel drill bits and lathe tools with Ra ≤1.2μm surface finish.
Construction Steel Prep: Prepares I-beams and rebar for galvanizing in bridge construction projects
