Frequently Asked Questions
What helix angles are available?
Common helix angles are 30° and 40°, with 2-hole or 3-hole configurations. Other angles are possible on request.
Which rod diameters and lengths do you stock?
Standard diameters and 330 mm lengths are available in common grades; cut-to-length and chamfered ends are supported.
Are the rods ground or unground?
Do you support custom sizes for helical coolant hole rods?
Yes. We produce to your drawings (PDF, DWG or STEP). Send specifications and our engineers will confirm feasibility and provide a quote within 24 hours.
What is the typical lead time?
Standard items are usually shipped in 7–15 days after order confirmation. Custom parts depend on complexity and are confirmed with the quotation.
