Achieve clean, rapid cuts with minimal burr formation and zero heat discoloration. Designed for right-angle grinders, this 4-1/2" x .045" Type 27 SLITTER A-SOLID cut-off wheel pairs an ultra-thin profile with a premium white aluminum oxide abrasive (A-46-R-BF) formulation. Featuring an integrated 5/8"-11 threaded hub, it spins directly onto standard grinder spindles for tool-free, spin-on wheel changes while delivering burr-free cuts across carbon steel, stainless steel, and alloy metals.
Key Features
-
Ultra-Thin .045" Cutting Profile: Minimizes surface contact and friction to deliver fast slicing with minimal material loss, low heat buildup, and minimal burr formation.
-
Premium White Aluminum Oxide Grain: High-purity, friable grain structure micro-fractures during operation to expose continuous sharp cutting edges, reducing discoloration on heat-sensitive alloys.
-
Tool-Free 5/8"-11 Threaded Hub: Eliminates the need for separate flange nuts and spanner wrenches—spins directly onto standard 4-1/2" angle grinder spindles for rapid wheel swaps.
-
Depressed Center Type 27 Profile: Provides additional clearance around the hub, preventing spindle nuts and mounting hardware from gouging the workpiece during flush cutting or close-quarter joint work.
-
Resinoid-Bonded Dual Fiberglass Reinforcement (BF): Engineered with high-strength fiberglass mesh to maximize wheel integrity and resist flexing or chatter at speeds up to 13,300 RPM.
-
A-46-R-BF Specification: Medium 46-grit grain size combined with a hard "R" resin bond balances aggressive stock removal with extended service life.
