6. FAQ Frequently Asked Questions
Q1: What is MOQ? A: Minimum order quantity is 1 piece. Mixed‑diameter sample set is available for press test.
Q2: What is delivery lead‑time? A: Stock standard‑size bits: ship within 3 working‑days after payment. Special‑custom shank / special‑length bits: 12‑16 working‑days.
Q3: What customization service do you provide? A: Custom total‑length, custom shank size (straight‑shank / taper‑shank), special‑hardness HSS material, OEM‑label packing for reseller.
Q4: Logistics & shipping options? A: Courier: DHL, TNT, FEDEX, UPS, EMS. Large‑volume bulk‑order choose sea‑freight or air‑freight. Payment terms: T/T, Western Union, Paypal.
Q5: Punch hole has burr / paper‑tearing phenomenon? A: Check: 1) Drill‑bit cutting‑edge is blunt, needs sharpening; 2) Drilling‑pad is worn‑out; 3) Too‑fast feeding‑speed. Replace backing‑pad or re‑sharpen drill‑bit.
Q6: Small‑diameter drill bit broken quickly? A: 3‑4 mm bits belong to delicate thin‑wall hollow‑structure; strictly forbid side‑force, offset‑load or violent impact. Breakage caused by improper operation will not be accepted for return.
Q7: Can I drill hard cardboard or wood material? A: Designed mainly for paper, cardboard, PVC and synthetic‑leather; not for solid‑wood or hard‑metal drilling. Wood‑drilling will quickly blunt cutting‑edge.
