Werner Wilke turning blank (DIN 4964 Form B) — HSS‑EW9Co10, square 25 x 25 mm, L 200 mm

Werner Wilke turning blank for precision turning, manufactured to DIN 4964 Form B for use in toolmaking and workshop turning operations

• HSS‑EW9Co10 with 10% cobalt for toughness
• Hardened to 65–69 HRC for long tool life
• Square 25 x 25 mm cross‑section, tolerance h13
• Length 200 mm, straight ends, finish ground

Engineered for consistent turning performance

The turning blank is manufactured from HSS‑EW9Co10 (material number 1.3207), a high‑speed steel alloy containing 10% cobalt, which raises hot hardness and improves wear resistance during demanding cuts. The heat treatment resulting in 65–69 HRC hardness delivers a robust core suitable for repeated roughing passes, while the body being finish‑ground ensures uniform section geometry for predictable clamping. These characteristics translate into fewer regrinds and reduced set‑up adjustments on lathes and automatic centres.

Dimensional certainty that supports fixture and chucking decisions

Produced to DIN 4964 in Form B (square), the bar features a 25 x 25 mm cross‑section with a h13 tolerance and a length of 200 mm with a length tolerance of +/- 2 mm. The combination of cross‑section precision and clearly specified length tolerance simplifies jigs, collet and chuck selection and reduces trial fitting. Ends are supplied straight and unground, which is advantageous for controlled facing operations or for custom end‑preparation prior to final mounting.

Material, treatment and workshop benefits explained

Using HSS‑EW9Co10 provides higher red hardness compared with standard HSS, making the bar suitable where elevated cutting temperatures occur. The material is hardened, tempered and finish‑ground, offering a balance between hardness and toughness: hardness gives cutting edge support; toughness resists chipping under interrupted cuts. For practical workshop planning, these metallurgical properties mean fewer workpiece rejects and improved repeatability when producing turned components from medium‑duty steels and alloyed materials.

Suitable applications and handling recommendations

This square turning stock is intended for master bars, customised tool bits and small component batches where square cross‑sections speed up milling or slotting operations prior to turning. The finish ground body enables immediate machining with predictable thermal behaviour; however, as the ends are unground, final facing or centring is recommended before precision finishing. The product’s measured tolerances and alloy composition make it an appropriate choice for pro‑tool rooms, small subcontractors and precision workshops seeking consistent blanks for short to medium production runs.

FAQ

What material is the bar made from and why does it matter?
The bar is made from HSS‑EW9Co10 (1.3207); the cobalt content increases hot hardness and wear resistance, which benefits continuous turning and intermittent cuts.

Is the cross‑section guaranteed for fixture fitting?
Yes, the square cross‑section is specified as 25 x 25 mm with tolerance h13, providing predictable fit for collets and clamps.

Can the blank be used immediately in precision turning centres?
The body is finish‑ground, so the blank is ready for most machining operations; final end‑facing or centring is recommended because the ends are supplied unground.

What does the hardness range mean for tool life?
A 65–69 HRC hardness provides durable edge support and wear resistance, which equates to longer service life under typical workshop cutting conditions.

Which standard and form apply to this turning stock?
Manufactured to DIN 4964, Form B (square), suitable where standardised dimensions and interchangeability are required.
