Bonded Solutions Built for Industrial Metalworking
Klingspor Abrasives’ Bonded portfolio brings together Cut-Off Wheels and Grinding Discs in a coordinated abrasive family designed for fabricators, maintenance professionals, and industrial users working across a wide range of materials and applications. From steel and stainless steel to aluminum, non-ferrous metals, cast materials, and hardened steels, these bonded solutions support cutting and grinding tasks on angle grinders, gas-powered saws, stationary machines, die grinders, and small cut-off tools.
By consolidating coverage into one portfolio, Klingspor helps distributors and end users cover virtually every cutting and grinding application while simplifying purchasing, product selection, and inventory management.
Bonded Cut-Off Wheels: Application Coverage and Control
Within the Cut-Off Wheels line, Klingspor offers a broad range of Kronenflex cut-off wheels featuring bonded abrasive construction with reinforced synthetic resin design. This structure supports stable, controlled cutting with reduced breakage risk and safer operation at high RPMs in industrial environments.
The portfolio includes ultra-thin and multi-purpose solutions such as the A 46 TZ SPECIAL for aggressive stainless and carbon steel cutting with minimal kerf, the A 946 TZ SPECIAL for shops processing a mix of stainless and carbon steels, and the A 60 TZ SPECIAL for stainless sheet, carbon steel, and container construction cutting.
Specialty wheels like the A 60 N SUPRA for non-ferrous metals, aluminum, copper, and brass feature a soft structure that prevents loading and glazing, while Ceramic K 960 TX SPECIAL and Alumina Zirconia Z 960 TX SPECIAL deliver aggressive cutting in demanding stainless, container, and hardened steel applications.
Aluminum Oxide A 960 TZ SPECIAL promotes fast burr-free cuts on stainless and carbon steel sheets, and Aluminum Oxide A 980 TZ SPECIAL, Klingspor’s thinnest wheel, delivers the narrowest kerf for precision cutting and minimal material loss.
Bonded Abrasive Reference Chart
A Bonded Abrasive Reference chart further supports selection by identifying ideal and possible applications for each wheel type and material, helping sales teams and end users reduce trial-and-error and gain confidence that the correct wheel is specified for each job.
Cut-Off Wheels for Tools, Machines, and Specialty Tasks
To support small-tool and machine-based applications, Klingspor extends its cut-off offering with compact and machine-rated solutions. The A 660 R SMALL CUT-OFF WHEELS in 2‑inch and 3‑inch sizes fit smaller tools and tight spaces for intricate cutting, trimming, and detail work, paired with the A 660 R MANDREL accessory for secure mounting of small diameter discs on hand-held or specialty tools.
For general-purpose cutting on hand-held machines, the A 24 R SUPRA serves steel, structural steel, tool steel, and sheet steel, while the A 24 R SUPRA for stationary machines is rated for stationary saws above 4 HP (3 kW) to support consistent performance in high-duty cutting and repetitive production workflows.
The A 924 R SPECIAL delivers robust cutting on steel, ductile iron, structural steel, and tool steel, and the A 924 SX SPECIAL is optimized for railroad tracks and steel, providing high- output cutting for rail and track applications on high-powered saws.
For chopsaws below 4 HP (3 kW), the A 330 E EXTRA universal cut-off wheel, A 630 N SUPRA FAST CUT marketed for fast cutting, and A 930 N SPECIAL provide general-purpose capability, shorter cut times, and enhanced performance on metal stock. The TS 30 AP SPECIAL supports pipe fabrication, stainless and carbon steels, along with light grinding, notching, and safe cutting in a single disc, while Duplex A 46 VZ SPECIAL offers an extra-thin dual-use wheel that allows users to move between cutting and safe grinding without changing tools.
Across the cut-off portfolio, clearly listed max RPM ratings, multiple thickness options, and box quantity information help operators match discs to tool capabilities, balance speed and cut quality, and plan orders and stock levels effectively.
Bonded Grinding Discs: Material-Specific Performance
Klingspor’s Bonded Grinding Discs complement the cut-off wheel range with bonded abrasive discs suitable for use on compatible grinding machines across a variety of metals and applications. The A 624 R SUPRA, identified as the top disc in the industry for mild steel, is intended for steel, structural steel, tool steel, and sheet steel and is available in multiple diameters and hub configurations so users can select a disc that fits their grinder size and mounting style. Standard box quantities, listed max RPM values by size, and clearly defined item numbers and per-disc pricing support safe operation, accurate ordering, and easier inventory planning.
For stainless steel and steel processing, the A 30 M SPECIAL is a 2 + 1 high-performance grinding disc offered in 4‑1/2‑inch configurations with two mounting options, 10‑disc box quantities, and a 13,300 RPM rating, giving users a defined operating window and simplified stocking decisions. Stainless applications are further supported by the A 24 N SUPRA, intended for stainless steel, non-alloy stainless steel, and high alloy stainless steel, with multiple diameters and hub styles plus standard box quantities and size-specific max RPM values.
For cast iron, cast steel, and hardened steel, the A 624 T SUPRA offers several diameters and hub configurations, 10‑disc box quantities, and published max RPM values alongside specific ordering codes and pricing for demanding grinding operations.
Aluminum and non-ferrous grinding needs are met by the A 46 N SUPRA, which is intended specifically for aluminum and other non-ferrous metals and is available in multiple diameters and hub styles, supported by listed box quantities, maximum operating speeds, item numbers, and unit prices to ensure accurate selection, safe use, and efficient purchasing.
