The Din338 drill bits supplied by Danyang Tongyu Tools Co., Ltd. are manufactured from 4241, 4341, and 9341 steel alloys, selected for their balance of hardness and impact resistance. These bits are produced through rolling and surface polishing processes to reduce friction and improve chip evacuation during high-speed drilling. The geometry follows the DIN338 standard, ensuring compatibility with standard chucks and drill presses used in industrial settings.
The material composition aligns with common tool steel grades for general-purpose twist drills, though the supplier does not specify exact heat treatment parameters or Rockwell hardness values. Typical industry practice for similar steel grades involves tempering to achieve 58-62 HRC, but this cannot be confirmed for these products. The bits are not coated, and no surface treatments beyond polishing are mentioned.
These drill bits are commonly used in automotive component manufacturing, metal fabrication, and construction equipment assembly where consistent hole quality is required. Buyers typically order in bulk for production lines or maintenance workshops. Packaging is designed for transport efficiency, with bulk cartons or plastic trays. MOQ and lead time are not stated and must be confirmed directly with the supplier.

Sourcing Din338 from Danyang Tongyu Tools Co., Ltd. - China Import Guide
Before ordering, verify the exact steel grade and heat treatment process used, as performance varies significantly between 4241, 4341, and 9341. Request a sample to check edge sharpness, surface finish, and concentricity. Confirm whether the bits meet DIN338 dimensional tolerances and if material test reports are available. Do not assume compliance based on product name alone.
Lead time and Incoterms are not stated. Buyers should confirm whether FOB, CIF, or EXW terms apply and whether the supplier handles export documentation. Payment terms such as T/T or LC should be negotiated directly. Minimum order quantities are not disclosed, so inquire about flexibility for trial orders. Shipping from Jiangsu ports may reduce freight costs compared to inland origins.
Perform incoming inspection for diameter consistency, runout, and edge chipping. Use a micrometer and dial indicator to verify tolerances. Check for uniform polish and absence of burrs. Request a certificate of origin and packing list. For bulk shipments, consider third-party inspection services. Retain samples from each batch for quality traceability in production.
