1. Introduction

The 13-Piece TiN Coated Combination Drill and Tap Set represents the ultimate efficiency for modern metalworking and industrial maintenance. This comprehensive kit eliminates the need for separate drilling, tapping, and deburring tools by integrating all three functions into a single high-performance bit.

Each bit is manufactured from premium High-Speed Steel (HSS-M2) and enhanced with a Titanium Nitride (TiN) coating. This golden coating significantly increases surface hardness, reduces friction, and enhances heat resistance, allowing for faster cutting speeds and up to 3x longer tool life compared to uncoated bits. The 1/4" quick-change hex shank makes the set fully impact-ready and compatible with all standard power tools.

3. Core Applications (Rich Applications)

• High-Speed Metalworking: Optimized for one-step threading in aluminum, copper, brass, and mild carbon steels up to 5mm thickness.

• MRO & Site Maintenance: The go-to kit for HVAC technicians and mechanical engineers who need to quickly create or repair threads in electrical boxes, ductwork, or automotive frames.

• Impact-Ready Performance: Specially designed to withstand the torque of cordless impact drivers, ensuring precise alignment without the need for center punching.

• Dual-Market Versatility: Featuring both Metric and SAE standards, this 13pc set is perfect for global B2B distributors serving diverse engineering requirements.

4. Packaging & Wholesale Advantages (B2B Focus)

• Rugged Storage Solution: The set is housed in a heavy-duty Aluminum Case or a high-impact Plastic Carry Case with custom-fit internal slots to prevent bit collision during transit.

• Corrosion Protection: Each bit is treated with industrial-grade anti-rust oil prior to TiN coating, ensuring a shelf life of up to 3 years in standard warehouse conditions.

• OEM Customization: Since 1997, our factory has provided full OEM services. We offer Laser Etching on the hex shanks for your brand logo and customized retail packaging for large-volume wholesale orders.

5. FAQ (Frequently Asked Questions)

• Q: Why choose TiN (Titanium) coating over a bright finish?

  • A: TiN coating increases surface lubricity, which prevents "chip welding" (material sticking to the tool) and allows the bit to maintain its sharp edge even under the high heat generated by high-speed tapping.

• Q: Can these bits tap through thicker steel plates?

  • A: These bits are optimized for thin-walled sections (up to 5mm). For thicker industrial plates, we recommend using our individual heavy-duty machine taps from the XRTOOLS catalog.

• Q: What is the benefit of the 13pc dual-standard set?

  • A: It provides a "One-Stop Solution." Wholesalers find this set highly popular because it consolidates the most-used global thread sizes into a single, compact, and easy-to-sell SKU.
