Starlock Cutter Blade for Precision Cutting on Silicone and Soft Glazing Compound - Smooth, Clean Cuts on MultiMaster Tools, Mushroom Shape, 5-Pack - 63903245230

This was perfect for what I needed it for.

Good to work with the glass to cut it off from frame.. also good fore glazing and old caulking removal jobs

The mushroom shaped blade is easy to use and works well cutting caulk when removing insulated glass units from window frames. The attachment area will handle all brands of multi-oscillating tools. Fein makes less expensive mushroom blades but they only have the "star" type attachment. I was surprised that the blade section will loosen and detach from the attachment section. Good thing five blades are included because on a big job, you'll go thru several. Also I found that a 12V battery & multi-tool will heat up and stop working if pushed too hard cutting caulking. Despite this the blade gets the job done.

Seems durable and arrived promptly and well packaged

To expensive for the quality. , they’re tach welded so they break apart after a few uses , a solid weld would have made this a 5 star product . Cheap junk but expensive

Fit perfect on m18 multi tool

Fein is of the highest standards

Perfect for any job.
