These are very high quality twist drill bits that are designed primarily for drilling through hard metals (such as stainless steel). They are extremely sharp; sharper than average drill bits, so be very careful. Clamping your workpiece is especially important when using these bits, as they can “bite” into the material and snag much easier than average drill bits do.

If you break a bit, please obtain an exact replacement from Summit Tools or any other local dealer of Norseman drill bits(prices range from $2-$10 depending on the size of the bit), or contact John for details.
