For anyone doing metalworking, this SDT annular cutter is a serious game-changer. The 1-9/16 inch diameter with 1 inch cutting depth lets you drill clean, precise holes in steel up to ten times faster than regular drill bits. Made from tough high-speed tool steel, this thing is built to last through some serious use. The 3/4 inch Weldon shank fits securely in compatible tools without slipping. What's amazing about annular cutters is how they only cut the outer edge of the hole, which means less effort and cleaner results. The holes come out machine-finish quality - no need for reaming or additional work when you use proper lubricant. I've used mine for everything from structural steel to automotive work, and the difference in speed and quality is unbelievable compared to traditional bits. Each cutter has the size laser etched on the shank, so no more guessing or measuring to figure out which is which. You can even make overlapping holes, slotting holes, and edge cuts with these - so versatile! The cutting depth is perfect for most sheet metal and plate work I encounter. They stay sharp through multiple uses too - just make sure to use cutting fluid for best results and longevity. If you do any amount of metal drilling, upgrading to annular cutters will make you wonder how you ever managed with twist drills. This particular size is super useful for conduit, plumbing, electrical, and mechanical applications. The quality feels professional grade, not those cheap import cutters that dull quickly. Seriously, once you go annular, you'll never go back to regular drill bits for metal work!
