The Ryobi PBLAG01K1 bundles the PBLAG01B brushless 4-1/2 in. angle grinder with a 4.0 Ah HIGH PERFORMANCE battery and charger, making it a complete out-of-box solution for homeowners and DIYers new to the ONE+ platform. The brushless motor delivers up to 9,200 RPM for grinding, cutting, and surface prep tasks, while the included grinding and cutting wheels let you get started immediately. The 4.0 Ah HP battery provides extended runtime compared to entry-level 1.5 Ah packs, reducing interruptions during longer jobs like driveway crack prep or metal fabrication work.
What battery comes with the PBLAG01K1?
The kit includes one 18V 4.0 Ah HIGH PERFORMANCE lithium-ion battery and an 18V charger. The 4.0 Ah HP pack delivers more runtime and better sustained power under load than the standard 2.0 Ah batteries bundled with many entry-level kits.
What size discs does the PBLAG01K1 accept?
The grinder accepts 4-1/2 in. discs with a 5/8 in. x 11 UNC arbor thread. This is the industry-standard angle grinder arbor, so wheels from Diablo, Dewalt, Makita, and other major abrasives brands are compatible.
Is there a tool-only version of this grinder?
Yes — the PBLAG01B is the bare tool version of the same grinder without a battery or charger. It is priced lower and is ideal for buyers who already own ONE+ 18V batteries.
What tasks is this grinder best suited for?
The PBLAG01K1 handles grinding (rust removal, weld cleanup, concrete scarifying), cutting (tile, rebar, thin metal), and surface preparation. The included Type 27 guard is set up for grinding wheels and the Type 1 guard for cutting wheels — swap them based on the task.
Can I use this battery in my other Ryobi tools?
Yes. The included 4.0 Ah HP battery is compatible with all 300+ tools in the Ryobi ONE+ 18V platform. It works in drills, saws, impact drivers, and any other tool that accepts an 18V ONE+ battery pack.
