Double-Ended Coated Solid Carbide Center Drill Overview
This double-ended coated solid carbide center drill is designed for accurate centering, spotting and selected light chamfering operations in aluminum, copper, steel and selected alloy-steel workpieces. Its two usable cutting ends improve tool utilization, while the short, rigid geometry supports stable positioning before follow-up drilling. Standard 90° configurations are available, with selected 60° and 120° point angles reviewed according to the required center-hole form. Diameter, length, coating, edge preparation and marking can be configured for standard purchasing or OEM requirements.
Key Configuration
Two Usable Cutting Ends
The reversible double-ended construction improves tool utilization when both cutting ends remain suitable for use.
Rigid Centering Geometry
The compact cutting geometry supports controlled tool entry and accurate starting positions before drilling.
Application-Specific Coating
Coating and edge preparation can be selected according to aluminum, copper, steel or mixed-material requirements.
Key Product Advantages
Configurable Center-Hole Geometry
Pilot diameter, body diameter, included angle and overall length can be matched to the required center-hole form or customer drawing.

Product FAQs
Product-specific information about applications, double-ended construction, coating selection, available configurations and machining requirements for this solid carbide center drill.
What materials is this center drill designed for?
This center drill is designed for aluminum, copper, steel and selected alloy-steel applications. The cutting geometry, coating and machining parameters should be confirmed according to the exact workpiece grade, hardness and required hole condition.
What is the advantage of the double-ended design?
The double-ended construction provides two usable cutting ends in one tool. After one end reaches its wear limit, the tool can be reversed when the second end remains undamaged, helping improve tool utilization and inventory efficiency.
What operations can this center drill perform?
It is suitable for producing center holes, preparing accurate starting locations before drilling and creating selected shallow chamfers. Final suitability depends on the pilot diameter, included angle, required center-hole form and machining setup.
How should the coating be selected for different materials?
Low-friction coating or polished cutting-edge options can be reviewed for aluminum and copper, while wear-resistant PVD coatings can be selected for steel and alloy steel. One coating may not provide the best performance across every material, so the primary workpiece should be identified before ordering.
What sizes and configurations are available?
Standard and custom configurations can be reviewed according to the product series. Pilot diameter, body diameter, cutting length, overall length, center angle and shank dimensions should be confirmed before ordering.
What information is required for a quotation?
Please provide the pilot diameter, body diameter, center angle, overall length, workpiece material, coating requirement and estimated quantity. A drawing or sample specification is recommended for custom center-hole profiles or non-standard dimensions.
Ordering & OEM FAQs
General information for trial orders, mixed-size purchasing, private labeling and production scheduling.
Do you accept small trial orders?
Yes. Small sample or trial orders are welcomed for dimensional verification and machining evaluation before committing to volume purchasing.
Can mixed sizes and coating options be ordered together?
Yes. Different standard or custom sizes can be combined in one order when the production and coating requirements are compatible. Mixed-size ordering is suitable for distributors, resellers and batch inventory planning.
Is OEM laser marking available?
Yes. Custom laser marking such as a logo, model number, size or batch identification can be reviewed together with OEM labels, individual packaging and outer-box requirements.
What is the typical production lead time?
Standard stock items normally have a shorter lead time, while custom dimensions, special coatings and OEM packaging require additional production time. The exact schedule is confirmed according to specification, quantity, coating and current production capacity.
