In today’s fast-paced manufacturing environment, reducing cycle times without compromising quality is paramount. Enter the Combination Drill and Tap Bit for M3 Threads, a game-changing tool that integrates drilling and tapping into a single operation. Designed specifically for soft metals like aluminum alloys and copper, this tool leverages advanced materials and precision engineering to deliver unmatched productivity.
Innovative Design for One-Step Processing
The patented design features a drill bit at the front end (Ø2.5mm for M3 threads) followed by a spiral flute tap, enabling continuous drilling and threading in one pass. Key advantages include:
65% Time Savings: Eliminates tool changes between drilling and tapping.
Perfect Hole Alignment: Ensures thread concentricity within ±0.02mm.
Chip Evacuation Mastery: 30° spiral flutes prevent clogging in gummy materials like 6061-T6 aluminum.
Material Excellence: 6542 High-Speed Steel
Crafted from HSS 6542 (Co5%), this bit offers:
Red Hardness of 62 HRC: Maintains edge integrity at 400°C.
15% Higher Toughness: Compared to standard HSS, reducing breakage risks in interrupted cuts.
TiN Coating Option: For extended life in abrasive cast iron applications.
Automotive HVAC Case Study
A supplier machining 10,000+ aluminum compressor brackets monthly reported:
Cycle Time Reduction: From 45 to 15 seconds per hole.
Tool Life: 3,500 holes per bit vs. 1,200 with separate drill/tap tools.
Zero Cross-Threading Defects: Achieved via self-centering drill geometry.
