Review on 🔩 THINKWORK Double Edged Titanium Straight Drill by Conrad Greene

I am a professional glazier. Basically I bought this for an M35 Cobalt Step Bit and it works GREAT. I don't really need the m35 step cutter and the HSS is enough as I only use it for through holes in aluminum profiles, but I'm very glad I bought it. I've used both of these attachments and found that the M35 cuts much better.
