Ryobi ONE+ HP 18V Brushless 4-1/2 in. Angle Grinder (Tool Only)

Model number
PBLAG01B

The Ryobi PBLAG01B is an 18V ONE+ HP brushless 4-1/2 in. angle grinder built for cutting, grinding, and surface preparation without a cord. Its brushless motor spins the disc at up to 9,200 RPM and delivers consistent power through heavy grinding tasks like weld cleanup, rust removal, and tile cutting. A spindle lock and FIXTEC nut make disc swaps fast, while the Type 27 and Type 1 guards included in the box support both grinding and cutting wheel configurations. As a tool-only purchase, it is ideal for ONE+ 18V battery owners who want to add a grinder to their arsenal without paying for redundant batteries and a charger.

§ FAQ

Does the PBLAG01B come with a battery?

No. The PBLAG01B is the bare tool only — no battery or charger is included. It is compatible with any Ryobi 18V ONE+ battery. If you need a battery and charger, consider the PBLAG01K1 kit, which ships with a 4.0 Ah HP battery and charger.

What size discs does the PBLAG01B accept?

The grinder accepts 4-1/2 in. discs with a 5/8 in. x 11 UNC arbor thread. This is the standard angle grinder arbor size, so most Type 27 grinding wheels and Type 1 cutting wheels from any major abrasives brand will fit.

How fast does the PBLAG01B spin?

The no-load speed is 9,200 RPM, which is in line with most corded 4-1/2 in. angle grinders and sufficient for aggressive grinding, rust removal, weld cleanup, and cutting through tile or thin metal.

Will the PBLAG01B work with my older Ryobi ONE+ batteries?

Yes. The PBLAG01B is compatible with all Ryobi 18V ONE+ batteries across the 300+ tool platform, including older standard batteries and newer HIGH PERFORMANCE packs. For best performance and runtime, Ryobi recommends the HP series batteries.

What is the difference between the PBLAG01B and the PBLAG02B?

Both are 18V HP brushless 4-1/2 in. angle grinders at 9,200 RPM, but the PBLAG02B is purpose-built as a cut-off tool with an angled grip that keeps hands clear of sparks during overhead or vertical cuts. The PBLAG01B is the standard flat-profile grinder suited to a broader range of grinding and cutting tasks.
