Duke Tools 6 Piece Metric Drill Tap Bit Set
Professional Metric Drill Tap Bit Set: Titanium-Coated HSS for Impact Drivers
Duke Tools 6 Piece Metric Drill Tap Bit Set
Titanium Nitride (TiN) coated HSS 4341 provides 3x longer tool life versus uncoated bits.
Product Description
Engineered for efficiency in metalworking, the Duke Tools 6 Piece Metric Drill Tap Bit Set integrates drilling and tapping into a single operation, minimizing setup time and tool swaps during fabrication tasks. Constructed from HSS 4341 alloy steel with a titanium nitride (TiN) coating, these bits exhibit enhanced hardness (up to HRC 62-64 post-heat treatment) and superior edge retention under high-friction conditions, as per industry standards for high-speed steels suitable for alloys up to 300 HB Brinell.
The 1/4″ hex shank ensures compatibility with quick-change systems in cordless drills and impact drivers, supporting torque loads up to 50 Nm without shank deformation. Ideal for threading in aluminum extrusions (6061-T6 grade), copper tubing, and mild steel (up to 1018 grade), this set addresses common challenges in prototype assembly and repair work by producing clean, burr-free threads with a 135° split-point geometry that initiates cuts without pilot holes. Users report up to 30% faster cycle times compared to separate drill-and-tap workflows, based on comparative tests in light industrial applications.
Key Features & Benefits
- Integrated Drill-Tap Design: Combines fluted drilling with tapered threading for seamless hole preparation and thread formation, reducing operational steps and enhancing workflow precision in constrained spaces.
- Titanium Nitride (TiN) coated HSS 4341 Construction: Provides 3x longer tool life versus uncoated bits through improved lubricity and heat dissipation (up to 600°C threshold), minimizing galling on non-ferrous metals.
- Universal Shank Compatibility: 1/4″ hex design locks securely in magnetic quick-change adapters, enabling use with variable-speed tools for controlled penetration rates of 200-500 RPM.
- Precision Metric Sizing: Covers M3x0.5 to M10x1.5 threads with ISO 965-1 compliant pitches, ensuring accurate mating with standard metric fasteners in automotive and plumbing assemblies.
- Versatile Material Handling: Optimized flute geometry evacuates chips efficiently in ductile materials, preventing binding and supporting blind-hole applications up to 3x diameter depth.

FAQs & Technical Guide
Get expert advice, in-depth answers, and practical tips to make the most of your Duke Tools 6 Piece Metric Drill Tap Bit Set. This guide addresses common queries on selection, operation, and maintenance to optimize performance in precision threading tasks.
What is the correct RPM range for using these bits on aluminum?
For aluminum alloys like 6061, maintain 400-600 RPM with a peck drilling technique—advance 2-3 mm, retract to clear chips, and re-engage. This prevents heat buildup exceeding 200°C, which could soften the TiN coating. Always apply a light machining oil for chip evacuation.
Can these bits handle stainless steel, and what limitations apply?
Limited to austenitic grades (e.g., 304) up to 2 mm thickness at reduced speeds (200-300 RPM). For deeper or harder steels (e.g., 316), use separate tools to avoid bit fracture; the HSS 4341 composition excels in softer metals but risks work-hardening in stainless.
How do I select the right bit size for a specific thread?
Match the nominal diameter and pitch to your fastener (e.g., M6x1.0 for 6 mm bolts). The integrated drill diameter is pre-optimized at 75-85% of major diameter for 65-75% thread engagement, per ISO 273 standards—consult a drill-tap chart for verification.
What lubrication is recommended to extend bit life?
Use a sulfur-based cutting fluid or WD-40 equivalent for ferrous metals; for non-ferrous, a light mineral oil suffices. Apply via drip or mist to maintain a coefficient of friction below 0.5, reducing torque by 20-30% and preventing built-up edge formation.
How should I store these bits to prevent corrosion?
Keep in the provided case away from humidity; the TiN coating resists oxidation, but wipe shanks with isopropyl alcohol post-use. Avoid magnetic storage to prevent edge nicks—shelf life exceeds 5 years under dry conditions
What torque settings are safe for impact drivers with this set?
Limit to low (10-20 Nm) for initial drilling, medium (25-35 Nm) for tapping. The hex shank withstands intermittent impacts up to 50 Nm, but monitor for vibration-induced chatter, which can dull flutes after 50-100 cycles.
