Titanium-Coated Tap Bit Set
6-Piece HSS Titanium-Coated Combo Tap Drill Set — Drill / Tap / Deburr 3-in-1
3-in-1 Functionality
Each bit completes drilling → tapping → chamfering in a single operation, minimizing tool changes and saving time. Suitable for materials like copper, brass, aluminum, plastic, and thin steel sheets.
Quick-Change Hex Shank
Features a 6.35 mm (1/4") hex shank compatible with electric drills, impact drivers, bench drills, screwdrivers, and tapping tools for easy and secure bit changes.
Durable HSS + Ti Coating
Crafted from HSS 4341 high-speed steel and finished with a titanium (gold) coating for enhanced sharpness, heat resistance, and cutting performance.
Anti Over-Drill Design
The tapered tip absorbs impact while the rear taper prevents excessive drilling and helps protect the threading for smoother operation.
Complete Metric Set
Includes M3×0.5, M4×0.7, M5×0.8, M6×1.0, M8×1.25, and M10×1.5 sizes. Each piece is clearly laser-marked for quick identification.
Made for On-Site Jobs
Perfect for tasks involving metal sheets, repairs, installation, and DIY where quick hole creation and threading are needed on soft metals or plastic.

FAQ
Q1: Can these be used on stainless steel?
A: These are ideal for non-ferrous metals and mild sheet steel. For harder stainless or thick metal, opt for cobalt-grade bits and operate at low speeds with sufficient cooling.
Q2: What speed is recommended?
A: Low RPM is best (typically 300–800 RPM on a hand drill). Always use cutting fluid and apply steady, light pressure while clearing chips regularly.
Q3: How can I avoid stripped threads or broken bits?
A: Start with a center punch and maintain a 90° angle. For thin sheets, complete the tap in one smooth pass if possible. During tapping, advance 1–2 turns, then reverse half a turn to clear chips—avoid forcing it.
Q4: Is separate chamfering needed?
A: The built-in deburring tip lightly chamfers during tapping, helping guide threads more smoothly.
Q5: Any special chuck required?
A: The 1/4" hex fits directly into quick-change chucks. For standard 3-jaw chucks, tighten firmly on the hex shank and eliminate any play to prevent slippage.
