Because we plate our own diamond products, we can offer the absolute best drums at better prices than anyone else. The diamond coating on your Inland diamond drill bit will never peel from the drum, or we’ll replace it for free for the life of the diamonds. You will never need to knock off the “bunchings” on an Inland bit—we don’t call them bunchings, we call them defects—and our quality control system eliminates them.
- Make either 1/8″ (3 mm), 1/4″(6 mm) or 3/8″ (10 mm) holes depending on choice of drill bit

- Use also to grind and shape intricate detail or tight curves
