3D/5D DLC-Coated Solid Carbide Twist Drill Overview
This DLC-coated solid carbide twist drill is designed for 3×D and 5×D hole machining in aluminum alloys and selected non-ferrous materials. Its two-flute, high-helix geometry provides chip space for ductile materials, while the low-friction DLC coating helps reduce aluminum adhesion and built-up edge under suitable cutting conditions. Standard diameter groups are available for regular purchasing, while length, coolant configuration, shank, laser marking and packaging can be reviewed for custom or OEM requirements.

Aluminum Drilling Guidance
- Length Selection: Choose the shortest 3×D or 5×D configuration that fully covers the required hole depth.
- Blind-Hole Allowance: Confirm flute length separately from usable hole depth and allow additional space for the drill point and chip accumulation.
- Lubrication & Chip Evacuation: Use suitable lubrication, air or coolant delivery to reduce aluminum adhesion and support chip evacuation.
- Coolant Configuration: Confirm through-coolant feasibility separately, particularly for smaller cutting diameters.
Recommended Starting Cutting Parameters
Starting values should be selected according to the exact aluminum grade, drill diameter, hole depth, coating, coolant delivery and machine rigidity.

Product FAQs
Product-specific information about applications, available configurations, customization and machining requirements for this carbide drill.
What materials and applications is this drill designed for?
This product is positioned for Aluminum Alloys, Non-Ferrous Materials. Final suitability should be confirmed from the exact workpiece grade, hole type, diameter, depth and machining conditions.
Why is DLC coating useful for aluminum-alloy drilling?
DLC provides a low-friction surface that can help reduce aluminum adhesion and built-up edge, supporting cleaner chip flow and more consistent hole quality.
What sizes and configurations are available?
The product is offered around the stated 3D/5D configuration. Other diameter, flute-length, overall-length or shank requirements can be reviewed according to the confirmed specification.
What coolant method can be used?
External coolant, air blast or mist can be selected according to the machine and workpiece. The main goal is to keep chips moving freely and limit material adhesion at the cutting edge.
Which surface treatment is specified for this product?
This product is specified with DLC coating. The low-friction surface is particularly relevant to aluminum and other non-ferrous applications where chip adhesion can be a concern.
What information is required for a quotation?
Please provide required diameter, hole depth or reach, workpiece material, coating requirement, and estimated quantity. A drawing is recommended for custom or non-standard requirements.
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 testing and performance evaluation before committing to volume purchasing.Can mixed sizes be ordered together?
Yes. Standard and custom sizes can be combined in one order when the production and coating requirements are compatible. Mixed-size purchasing is useful for distributors and batch inventory planning.Is OEM laser marking available?
Yes. Custom shank laser marking such as logo, model number, specifications, or batch identification can be reviewed together with OEM labels and packaging requirements.What is the typical production lead time?
Standard stock items normally have a shorter lead time, while custom tools and special OEM orders require additional production time. The exact schedule is confirmed according to specification, quantity, coating, and current production capacity.Downloads & Technical Resources
