Skh51 Drill Blank Supply Straight Ground Rounds Sized Ready For Fluting - China

SKH51 Drill Blanks – Straight, Ground And Sized For High-Volume Drill Production Drill manufacturers judge a blank supplier by three things: straightness, tolerance stability and heat-treatment predictability.

Songshun supplies SKH51 drill blanks (JIS standard, equal to AISI M2, DIN 1.3343 and GB W6Mo5Cr4V2) engineered exactly for those three criteria, serving drill makers across Asia, Europe and the Americas.

Drill blank specifications:

- Diameter: 1.0 – 40mm, centerless ground, h7 tolerance standard (h8 on request)

- Straightness: better than 0.1mm per 300mm — critical for deep-hole drills and long series

- Lengths: 1000 / 2000 / 3000mm mill lengths, or cut-to-length per your fluting schedule

- Condition: fully annealed HB 255 max, surface free of decarb, seams and scale Why drill factories choose our blanks:

1 - Clean fluting: fine carbide distribution from 7000-ton press forging means the milling cutter runs smoother and flute edges stay crisp.

2 - Stable hardening: locked chemistry per heat (C 0.80–0.90 / Cr 3.80–4.40 / Mo 4.50–5.50 / W 5.50–6.75 / V 1.75–2.20) keeps your vacuum quench at 1200–1240°C and triple temper at 550–580°C producing HRC 63–65 every batch.

3 - Less grinding after hardening: uniform starting diameter and low distortion reduce final OD grinding time noticeably.

4 - Traceability: heat number on every bundle tag, mill certificate with each shipment, UT reports for larger sections.

Production support we add at no cost:

- Advice on expected size growth between annealed and hardened condition for your drill geometry

- Split deliveries to match your fluting line schedule

- Trial quantities from 10 pieces for first qualification Stock diameters dispatch within 48 hours; cut-to-length blanks in 3–7 working days.
