Working with thin 304 stainless steel sheets—especially those between 0.5 mm and 3 mm—is notoriously difficult. The material’s rapid work hardening and heat buildup during drilling often lead to broken taps, ruined threads, or deformed sheets. The M35 combination drill and tap bit (a single tool that drills and threads in one operation) overcomes these problems through aerospace-grade precision and advanced thermal management.
Core Technologies Behind the M35 Bit
Variable Helix Tapping Flutes (45°/35°)
Alternating flute angles suppress harmonic chatter, which is critical when cutting thin, resonant stainless steel sheets. This design also improves chip evacuation and reduces friction.
Cryogenically Treated M35 High-Speed Steel
The deep cryogenic treatment refines the carbide structure, boosting wear resistance by 50% compared to conventional M2 HSS. This translates directly to longer tool life when machining abrasive 304 stainless.
Through-Hole Optimization (10° Exit Angle)
A specifically engineered 10° exit angle minimizes burr formation on the underside of sheet metal. For thin sheets (0.5–3mm), this eliminates the need for secondary deburring operations.

Pro Tip for 304 Stainless Steel Sheets
When using the M35 combination bit, maintain a pecking cycle (every 0.5mm depth) to break chips and reduce work hardening. For 0.5–1mm sheets, use a backing plate (e.g., aluminum or wood) to prevent exit burrs and sheet lift.
