Quick answer The BOSCH OSL350SPDK scores 8.4/10 with us. Amazon owners rate it 4.2 out of 5 across 432 reviews, in line with the 4.1 average of the 16 sanding pads we track. It was listed at $10.43 on Amazon when we last checked in September 2026.

The Bosch OSL350SPDK Starlock Oscillating Multi-Tool Delta Sanding Pad Kit features a triangular delta sanding pad to attach triangle-shaped sheets designed for detailed sanding. This pad features the Starlock three-dimensional tool-accessory interface, which provides more contact area versus flat interface for best-in-class grip and highest torque transfer. Sanding with a multi-tool often requires access to hard-to-reach areas at difficult angles.

These Bosch sanding triangles also meet the need for material removal and surface finishing on multipurpose plywood, hardwoods and softwoods.

    Bosch multi tool bi-metal blade

    Construction duty. Goes through wood and nails fast. Have to use entire surface or middle of the blade will burn out fast cutting metal. Best price found on Amazon.

    Quality durable blade; excellent control.

    Excellent quality; knock off nlades don’t compare. This 2.5” wide cut gives you great control when making a straight cut. I’ve been using fein blades with my Fein oscillating tool for 20 years; 2006 I bought my first Fein tool; I have a corded model and a battery operated on; to be honest my corded one pretty much stays in my truck box…lol

    Hook-and-loop fails immediately — pads fly off within minutes

    Terrible hook-and-loop adhesion. I burned through three sanding sheets in less than 10 minutes because the pads simply will not stay mounted to the backing block. Even under light pressure, the paper constantly slips, bunches up, and flies off, rendering both the paper and the pad practically useless right out of the box. Extremely disappointing quality from Bosch—save your money and look elsewhere.

    Very effective and versatile.

    Bosch quality. If you are cutting alloy steel or stainless, this is not your blade. Get the carbide. This is good for everything else.

    Might not work with your Makita Starlock Mutlitool

    The pad and sanding disc disintegrated when used with the black makita compact star lock multitool.Update: I got curious and I’ve seem to have discovered i have to drop the speed down to 2 on my tool to get these to, “work”. If your tool has an adjustable speed setting or dial; these do NOT disintegrate at a lower speed. Maybe it’s the adhesive of these pads idkI haven’t found any that work at high speed yet. They seem to barely hold on.
