Twist Drill for Brass & Copper
This straight-shank solid carbide twist drill is designed for stable blind-hole and through-hole machining in brass, copper and selected copper alloys. Sharp cutting edges, smooth spiral flutes and a rigid fine-grain carbide body support clean cutting, controlled chip evacuation and repeatable hole production. The series is available in 3D, 5D and 8D depth configurations from Ø3.0 to Ø20.0 mm, with polished uncoated, DLC or application-specific surface options selected according to the exact alloy, hole depth and machining conditions.
Key Configuration
Precision-Ground Point
Application-matched point geometry supports stable positioning and controlled entry in brass, copper and related non-ferrous alloys.
Smooth 2-Flute Geometry
Two spiral flutes with a smooth cutting surface support chip evacuation in both blind-hole and through-hole machining.
Straight-Shank Construction
A cylindrical straight shank provides a simple, rigid clamping interface for compatible precision collets and CNC toolholders.
Key Product Advantages
Sharp Cutting for Non-Ferrous Metals
Sharp cutting edges help reduce smearing, material adhesion and built-up edge when drilling brass, copper and selected copper alloys.
Low-Friction Flute Surface
Polished uncoated or DLC-type surface options can be selected to support cleaner chip flow and reduce material sticking under suitable cutting conditions.
3D / 5D / 8D Depth Options
Three depth series allow the drill length to be selected according to the required hole depth while balancing rigidity and chip evacuation.
Fine-Grain Carbide Rigidity
The solid carbide body provides rigidity and dimensional stability for repeat CNC drilling across the Ø3.0–20.0 mm series.

Brass & Copper Drilling Guidance
- Brass: Use controlled point geometry to reduce grabbing. Air blast may suit free-cutting grades.
- Copper: Use sharp edges, smooth flutes and stable lubrication to limit built-up edge and material adhesion.
- Select the Shortest Suitable Series: Use 3D where possible, 5D for medium depth and 8D only when the required depth justifies the additional length.
- Control Chip Evacuation: Match air, MQL or coolant delivery to the exact alloy, hole depth and blind- or through-hole condition.
Recommended Starting Cutting Parameters
The original product page provides the following starting references. Adjust according to cutting diameter, depth series, alloy grade, machine rigidity, runout and coolant condition.
| MATERIAL | Vc (م/دقيقة) | FEED GUIDANCE | COOLANT / CHIP REMOVAL |
|---|---|---|---|
| Free-Cutting Brass | 120–200 | Stable feed; avoid excessive dwell | Dry cutting or air blast |
| Lead-Free / Tough Brass | 80–150 | Reduce speed for tougher grades | Air blast, MQL or coolant |
| Pure Copper | 60–120 | Use sharp edges and consistent feed | MQL or stable coolant |
| Bronze / Copper Alloy | 70–140 | Adjust for grade and abrasiveness | Air blast or suitable coolant |

Product FAQs
Product-specific information about solid carbide drilling in brass and copper, straight-shank clamping, cutting geometry, chip evacuation, surface configuration and application requirements.
What materials is this carbide drill designed for?
This drill is intended primarily for brass, copper and related non-ferrous metal applications. Final geometry and surface configuration should be confirmed according to the exact alloy, material condition, hole depth and required hole quality.
Why is a straight-shank design used?
A cylindrical straight shank provides a simple and stable clamping interface for precision collets and compatible CNC toolholders. Shank diameter and overall tool length should be matched to the holder, available machine space and required drilling reach.
How is the drill geometry different for brass and copper?
Brass and copper can require different cutting-edge and flute characteristics. Sharp cutting edges, controlled point geometry and a low-friction flute surface can be reviewed to support clean cutting and chip evacuation. The final design should be selected for the specific alloy rather than using one universal geometry for all non-ferrous materials.
Should the drill be coated or uncoated?
Uncoated or polished flute configurations are commonly reviewed for non-ferrous drilling because low friction and clean chip flow are important. A suitable low-friction coating, including DLC-type options where appropriate, can also be evaluated according to the alloy, production quantity and tool-life requirement.
What machining conditions are important when drilling brass and copper?
Low tool runout, rigid clamping, stable feed and reliable chip evacuation are important. Coolant, mist or air delivery should be selected according to the material, hole depth and machine setup. Copper applications in particular should be reviewed carefully for chip adhesion, heat and burr formation.
What information is required for a quotation?
Please provide the cutting diameter, hole depth, hole tolerance, brass or copper alloy grade, flute length, shank diameter, overall length, coolant condition, machine type and required quantity. A drawing is recommended for non-standard dimensions or special hole requirements.
Ordering & OEM FAQs
General information for trial orders, mixed sizes, OEM marking and repeat distributor supply.
Do you accept small trial orders?
Yes. Small trial quantities can be reviewed for hole-quality testing, chip-evacuation verification and tool-life evaluation before larger repeat orders.
Can mixed drill sizes be ordered together?
Yes. Different cutting diameters and length configurations can normally be combined in one order when the carbide, surface treatment and production requirements are compatible.
Is OEM laser marking available?
Yes. Logo, item code, drill size and batch identification can be reviewed for laser marking where the available shank area permits. Custom labels and private-brand packaging are also available for OEM orders.
What is the typical production lead time?
Lead time depends on diameter, flute length, surface treatment, custom geometry and order quantity. Final production scheduling is confirmed after the product specification and application requirements are approved.
