6-Piece Metric Combination Drill & Tap Bit Set

🔧 6-Piece Metric Combination Drill & Tap Bit Set — Drill and Thread with Fewer Bit Changes

Preparing a hole for a metric screw usually means reaching for both a drill bit and a tap. This combination set brings the drilling tip and thread-cutting section together, helping simplify compatible drilling and tapping jobs around your workbench, garage, or home workshop.

⚙️ Two Operations on One Bit

The leading tip drills the hole, and the tapping section behind it cuts the matching internal thread as the bit advances. Combining these functions reduces tool changes when the material and workpiece thickness suit the bit’s geometry.

🔩 A Hex Shank for Your Existing Setup

Each bit has a 1/4-inch (6.35 mm) hex shank for compatible drill chucks and bit holders. The shared shank size keeps setup consistent as you change thread sizes. Use controlled rotary operation; the hex shank alone does not indicate suitability for impact or hammer mode.

🛠️ Match the Bit to Your Project Material

The illustrated applications include wood, plastic, PVC, aluminum, and copper. Choose a suitable workpiece and confirm the recommended thickness and cutting conditions before starting. Thread strength and finish depend on the material, so test on a spare piece when working with a new application.

📏 Six Metric Thread Sizes to Choose From

The set is listed with M3 × 0.5, M4 × 0.7, M5 × 0.8, M6 × 1.0, M8 × 1.25, and M10 × 1.5 thread sizes. Match both the diameter and pitch to your screw before cutting. These are metric threads; the inch measurements in the illustration are dimensional conversions, not SAE thread equivalents.

The illustrated overall bit lengths range from 54 to 58 mm, approximately 2.13 to 2.28 inches. Overall length is not the usable drilling or tapping depth.
