Alpha DTMC030 M3 x 0.5 HSS TiN Combination Drill & Tap

The Alpha Combination Drill & Tap in metric coarse drills, taps and deburrs a hole in one operation. This listing includes six HSS, TiN coated sizes from M3 x 0.5 to M10 x 1.5, each with a 1/4" quick change shank (manufacturer-stated).

Alpha states that the tool drills, taps and deburrs ferrous and non-ferrous metals in one operation in material up to 3.5mm thick. The catalogue lists fully ground M2 HSS with a titanium nitride coating that reduces heat and increases lubricity, a 135° split point that cuts faster and reduces wandering, and a 30° helix angle.

Each size is supplied as a single carded tool, and the catalogue gives the drill size, flute length and overall length for every code. It suits power drills and impact drivers; the maker lists aluminium, steel and stainless steel as the materials.

Selecting the right option

Pick the thread size, then check the drill size column: it is the diameter of the hole the tool drills. All sizes work in material up to 3.5mm. For imperial threads see the UNC combination drill and taps, and for a mixed kit with matching drill bits see the 25 piece combination drill and tap set.
