Product detail · 详情说明
Cobalt drills are specified for stainless and alloy steel because standard HSS loses hardness at the cutting temperature. For taps, the flute form matters as much as the pitch: spiral-point taps push chips ahead in through holes, spiral-flute taps pull them out of blind holes.
State the material being cut, hole depth (through vs. blind), thread standard and pitch. We supply the matched drill diameter for the tap — an undersized tapping drill is the most common cause of broken taps.
选型与验收要点 / Selection & acceptance points
- Matched tapping-drill diameter supplied with each tap
- Spiral-point vs. spiral-flute selected for through or blind holes
- ISO metric / BSP / NPT / UNC thread standards distinguished
- HSS-Co5 / M42 and TiN / TiAlN coating options

Frequently Asked Questions
Send the part number, a photo of the nameplate / old part, or the machine model and required dimension. We reply with the applicable standard designation and a factory datasheet; the final specification is fixed on the proforma invoice.
Commercial invoice, packing list, certificate of origin, bill of lading or AWB, and an HS-coded technical datasheet. The HS 6-digit heading shown on this page is the international classification; your clearing agent confirms the Pakistan 8-digit PCT subheading and the duty rate applicable on the date of import.
No. The location named under 'Typical sourcing base' is a publicly known industrial cluster, given to help you understand the supply chain. The actual factory, country of origin and any mill / test certificate are confirmed in writing on the quotation and the certificate of origin. Treat it as [待确认] until then.
