Sealey SA152 Air Angle Grinder 100mm

The Sealey SA152 (139007) is a pneumatic 100mm air angle grinder built for professional use in automotive workshops, fabrication and general workshop environments. It runs at 12,000rpm free speed on 90psi working pressure and draws just 4cfm of air compatible with most standard workshop compressors. At 1.8kg it's genuinely light for a professional-grade tool.

The body is lightweight composite construction rather than metal. That matters because it cuts vibration transfer and eliminates the cold transmission you get with metal-bodied grinders during long sessions. The rear exhaust has a built-in noise-reducing baffle rated at 85dB(A) pressure quieter than most comparable air grinders.

Safety is well covered. The safety throttle lever prevents accidental activation when you set the tool down or pick it up. A spindle stop button makes disc changes fast using the M10 x 1.5mm threaded spindle. The included side handle gives solid two-handed control for grinding and cutting work. Spanners for disc fitting are also included.

The SA152 takes standard 100mm grinding discs (sold separately) and carries a 3-year Sealey manufacturer guarantee. For a pneumatic grinder aimed at trade use it ticks the right boxes light, quiet and properly specified.

The SA152 uses a pneumatic motor driven by compressed air at 90psi. It spins a 100mm disc at 12,000rpm free speed and draws just 4cfm low enough for most workshop compressors. The composite body is the key design choice here. It absorbs vibration and prevents the cold transfer you get from metal housings during long sessions. The rear exhaust baffle actively reduces noise output to 85dB(A). The M10 x 1.5mm spindle with a stop button makes disc swaps quick. No electronics this is a straightforward pneumatic tool built for reliability.

Always fit the correct guard use a grinding guard for grinding discs and a cutting guard for cut-off work. Check every disc is rated at 12,000rpm or above before fitting. Use the included side handle at all times for two-handed control. Wear eye protection, hearing protection and gloves. The safety throttle lever stops accidental starts keep your finger off it until ready to grind. Let the disc come to a full stop before setting the tool down.
