DIYers and machinists, these uxcell hand reamers are precision tools that deliver professional results! Each reamer has a 1/8 inch cutting diameter with H8 accuracy class - that's seriously precise for finishing holes. The 6-flute design provides smooth, clean cuts in various materials. Made from high-speed steel (HSS) that maintains sharpness through repeated use. The cutting length is 31mm with an overall length of 60mm, and the square shank measures 3mm for secure wrench grip. These are uncoated tools, making them suitable for aluminum, cast iron, copper, plastic, wood, and other soft materials. The straight flute design allows chips to collect neatly rather than clogging. Perfect for enlarging existing holes, repairing damaged threads, or achieving that final perfect fit in your projects. Using them is straightforward - just hand operate with a wrench for light cuts and repair work. Pro tip: always use machine oil during operation to extend the tool's life and keep things running smoothly. You get two reamers in the pack, which is great because these are tools you'll want to have on hand when needed. The quality is impressive for the price - much better than those cheap import tools that dull quickly. Whether you're working on automotive projects, metal fabrication, or precision woodworking, these reamers deliver the accuracy and durability you need. Keep your workshop stocked with quality tools that actually perform!
