Can I use one holder for different jobs?

Yes. Grooving, profiling, back boring, chamfering and threading heads of the same size fit the same holder.

Which holder should I choose?

Use the largest holder the bore allows. Steel and carbide anti-vibration holders are available, all with through coolant.

How do I read the head code?

Head size, operation, width, depth and minimum bore. For example 05GR100-1.4D07: size 05, grooving, 1.0 mm wide, 1.4 mm deep, for bores from 7.0 mm.

AI-Powered supplier vetting

SummaryCHANGZHOU DELEVEL TOOLS CO., LTD. is a China-based manufacturer/factory specializing in carbide drills, end mills, threading tools, modular tooling, and custom carbide tools. It reports ISO 9001 certification, more than 12 years of carbide-tooling experience, six production lines, six-to-ten R&D engineers, six-to-ten quality-control staff, and annual carbide end-mill output of 600,000 pieces. The supplier supports multiple customization modes, ODM, and OEM services for well-known brands, and reports inventory capability and off-peak lead times within 15 working days. However, written corrective-action and complaint-handling procedures are absent, overseas service infrastructure is limited, and the validity of manufacturing-capacity contracts and quality-assurance status is unknown. Financial-capacity entries are present for 2023–2025, but no sufficient non-monetary evidence establishes financial strength. Customer cases are not specifically documented.

Supplier typeThe supplier is explicitly identified as a Manufacturer/Factory and a limited company in China. Its listed products and business scope cover carbide and other metal tooling, consistent with a direct manufacturing supplier.

CertificationsThe supplier reports holding ISO 9001 certification for its management system. This is explicit evidence of a formal quality-management certification, although the slices do not provide certificate validity or scope details.

After-Sales capabilityThe supplier has no written procedures or records for corrective and preventive actions or effective complaint handling. It has inventory capability, but no overseas warehouse, showroom, agents, or branches; therefore, the documented after-sales framework is deficient despite some fulfillment support.

R&D capabilityThe supplier reports new products during the past year, ODM availability, and six-to-ten R&D engineers with total R&D experience stated at six-to-ten years. It lacks an available SDK, but the documented product-development and ODM activity supports innovation capability overall.

Production capacityThe supplier operates six production lines, reports 600,000 carbide end mills produced annually, employs six-to-ten quality-control staff, and states off-peak lead times within 15 working days. Inventory capability and a claimed on-time-delivery record further support production execution, although contract status and quality-assurance status remain unknown.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full and minor customization, flexible customization, ODM services, and custom carbide tools. Its stated specialization in non-standard carbide tools and technical support directly supports strong customization capability.

Product Q&A

Q:Do you have these in stock?

Stock depends on the code. Send the insert codes or groove sizes you need and we confirm stock and lead time; special profiles take 15-30 working days.

Q:What do you need for a quote?

The insert code, or the groove width, depth and diameter (or the part drawing), the workpiece material, your machine spindle or holder, and the quantity.

Q:Can you grind a special profile?

Yes. Special widths, radii and profiles are ground to your drawing from 5 pieces; we confirm the drawing before production.

Q:Which materials can they cut?

Steel, stainless steel, cast iron and non-ferrous metals. Tell us the material and we choose the insert grade and coating.

Q:What is the smallest bore?

Grooving starts at 5.5 mm bore diameter. The size table lists the minimum bore of each standard head.
