Detailed Description

Drilled balls combine a spherical outer surface with customized hole dimensions for connection, positioning, assembly and decorative requirements.



DRILLED BALLS

Drilled balls can be produced from stainless steel, carbon steel, chrome steel, brass, aluminum alloy and other suitable materials. Drilled steel ball is one of the most widely used types. Common options include through holes and blind holes, with dimensions confirmed according to the drawing or sample.

Drilled stainless steel balls feature good corrosion resistance and stable mechanical performance. Ball diameter, hole dimensions and surface finish can be customized for mechanical assemblies, connectors, decorative components, handicrafts and other special applications. As each customized project is different, other requirements for this drilled ball can be evaluated according to drawings, samples and application details.

FAQ
What are the key machining requirements for a drilled steel ball?
The drilled steel ball needs precise hole concentricity and smooth inner surface. We inspect every drilled steel ball to guarantee no cracks, meeting mechanical assembly and pressure resistance standards for industrial applications.
What certifications can you provide for bulk drilled stainless steel balls orders?
Our drilled stainless steel balls come with material test reports. Each batch of drilled stainless steel balls passes dimension checks, suitable for long-term use in corrosive working environments.
Can we customize the hole size and ball diameter of drilled balls for our project?
Yes, custom sizes are available. We support different hole depths and surface treatments. Send your drawing, we will quote quickly and arrange sample delivery for your testing.
What surface treatments are available for drilled balls to improve wear resistance?
We offer polishing, passivation and hardening treatments. These processes reduce surface friction and prevent rust, extending service life under continuous rotating and impact conditions.
What is your normal lead time for mass production of drilled balls after sample confirmation?
Standard orders take 10–18 working days. Rush orders can be supported. We strictly control production schedules and do full inspection before packaging and shipment.
How do you guarantee the consistency of hole position across large quantities of drilled balls?
We use CNC drilling equipment for stable machining. Random sampling inspection is carried out during production to keep high dimensional consistency for all finished drilled balls.
Can you provide samples?
Yes. Samples can be arranged after the material, ball diameter, hole dimensions and surface finish are confirmed. Sample cost and lead time depend on the specification.
