Black and Gold Oxide Finish - Tap and Drill Combination Tool

A NEW Product proudly made in the USA! Norseman Viking Seven Piece Drill and Tap Combination Bits save time, money and effort! Time is money. Drill once and get the job done. These high quality, high speed steel combo bits drill the hole and tap the threads in a single drill. The self-centering split point provides excellent drilling precision and accuracy. The seven most popular screw sizes are included from 8-32 to 1/4-20 to 1/2-13.

Black oxide treatment adds lubricity and creates small pockets on the surface of the bits that act to hold coolant near the cutting edge. Gold oxide treatment adds lubricity for ultimate cutting and bit performance. Combo drill and tap bits have round shanks with flats onto three sides to reduce slippage of the bit when used in drill chucks. Heat treated, split point bits are self centering, for precise drilling applications.

Ideally suited for on-site tapping construction applications, maintenance and repair, assembly, manufacturing and production environments. Convenient nylon pouch has velcro for easy open and close, and a buckle so that it can be easily clipped onto a belt. Not to be confused with a Tap and Drill Set, which includes an individual drill bit and separate tap. Free bottle of Ultra Cutting Lubricant included with purchase!
