Solid Carbide Twist Drill for Titanium & Heat-Resistant Superalloys Overview
This solid carbide twist drill is developed for titanium alloys and heat-resistant superalloys where concentrated cutting heat, material adhesion, work hardening and difficult chip evacuation can reduce drilling stability. Application-specific point geometry, edge preparation and flute design help control thrust, chip formation and cutting-edge loading during precision CNC hole machining. Fine-grain solid carbide, low-friction flute treatment and application-specific surface options support consistent hole quality in demanding ISO S materials. Standard 3×D, 5×D and 8×D configurations are available from Ø3.0 to Ø20.0 mm, with through-coolant versions recommended for deeper and more demanding applications.

Key Configuration
ISO S Material Geometry
Point geometry, edge preparation and flute design are selected specifically for titanium and heat-resistant alloy drilling.
Controlled Cutting Edge
A sharp but supported edge condition helps reduce rubbing and axial load while maintaining strength against chipping and rapid wear.
Coolant & Chip Control
External-coolant and through-coolant configurations can be selected according to drilling depth, chip flow, machine capability and alloy grade.
Key Product Advantages
Reduced Rubbing & Heat Concentration
Material-specific geometry and controlled edge preparation support a stable cutting action in alloys that are sensitive to heat and work hardening.
Low-Friction Chip Evacuation
Two spiral flutes and low-friction flute treatment help move difficult chips away from the cutting zone in blind and through holes.
Heat & Wear Management
Fine-grain carbide, edge preparation, flute treatment and application-specific PVD coating can be combined for concentrated heat and abrasive wear.
3D / 5D / 8D Application Range
Three depth series allow the drill configuration to be matched to rigidity, coolant access, chip control and the required hole depth.

ISO S Drilling Guidance
- Titanium Alloys: Use sharp cutting action, low-friction flutes, stable coolant delivery and continuous feed to limit adhesion, heat concentration and work hardening.
- Nickel-Based Superalloys: Use a supported cutting edge, conservative cutting conditions and reliable chip evacuation to control high cutting forces and rapid wear.
- 3×D: Recommended where maximum rigidity, stable chip evacuation and hole quality have priority.
- 5×D: Suitable for medium-depth holes with low runout, continuous feed and reliable coolant delivery.
- 8×D: Requires rigid toolholding, minimal runout, reliable chip control and preferably a through-coolant configuration.
- Avoid Dwell: Rubbing or pausing at the hole bottom can increase heat, promote work hardening and accelerate cutting-edge wear.
Recommended Starting Cutting Parameters
The original product page provides material-specific parameter strategy rather than fixed numerical speed and feed values. Final cutting speed, feed, coolant pressure and drilling cycle must be confirmed according to alloy grade, heat-treatment condition, drill diameter, hole depth, coating, machine rigidity and holder runout.
| WORKPIECE MATERIAL | MAIN CHALLENGE | PARAMETER STRATEGY | COOLANT GUIDANCE |
|---|---|---|---|
| Commercially Pure Titanium | Adhesion and long-chip formation | Controlled speed, stable feed, avoid rubbing or dwell | High-flow coolant recommended |
| Ti-6Al-4V / Grade 5 | Heat concentration and cutting-edge wear | Moderate cutting speed and continuous, non-rubbing feed | Through coolant preferred for deeper holes |
| Inconel 625 / 718 | Work hardening, high cutting force and rapid wear | Conservative speed, stable feed, avoid interrupted dwell | Through coolant strongly recommended |
| Hastelloy / Cobalt-Based Alloys | High-temperature strength and abrasive wear | Application-specific geometry and conservative starting conditions | Stable through-coolant supply preferred |

Product FAQs
Product-specific information about solid carbide drilling in titanium, nickel-based superalloys and other heat-resistant materials, including cutting heat, edge strength, coolant strategy and machining stability.
What materials is this carbide drill designed for?
This drill is intended for titanium alloys, nickel-based superalloys and other confirmed heat-resistant metal grades. Final carbide grade, point geometry, edge preparation, coating and cutting data should be selected according to the exact alloy, hardness, hole depth and machine conditions.
Why does titanium and superalloy drilling require a dedicated drill geometry?
Titanium and heat-resistant superalloys generate high cutting temperatures and can place heavy mechanical and thermal loads on the cutting edge. A dedicated point, flute profile, edge preparation and carbide grade can help balance cutting sharpness, edge strength, chip formation and wear resistance for these demanding materials.
Why is coolant control important when drilling titanium and heat-resistant alloys?
Reliable coolant delivery helps control cutting temperature, reduce material adhesion and support chip evacuation. As hole depth increases, coolant access to the cutting zone becomes more important. The required coolant method should be selected according to drill diameter, hole depth, alloy grade and machine capability.
What machining conditions are important for stable drilling?
Use a rigid CNC machine, low-runout holder, secure workpiece clamping and the shortest practical tool overhang. Stable feed, controlled entry and consistent coolant delivery are important because vibration, rubbing and interrupted chip evacuation can quickly increase cutting temperature and edge wear.
Can the geometry, coating and dimensions be customized?
Yes. Cutting diameter, flute length, shank diameter, overall length, point geometry, edge preparation, coating and coolant configuration can be reviewed according to the titanium or superalloy grade, required hole depth, tolerance and CNC setup. Non-standard tools can also be evaluated from drawings or existing samples.
What information is required for a quotation?
Please provide the cutting diameter, hole depth, blind-hole or through-hole requirement, workpiece alloy grade, hardness or condition, flute length, shank diameter, overall length, required tolerance, coolant method, machine type and 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 evaluation, dimensional verification and tool-life comparison 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 grade, geometry, coating and production requirements are compatible.
Is OEM laser marking available?
Yes. Logo, item code, tool 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 programs.
What is the typical production lead time?
Lead time depends on cutting diameter, flute length, coating, coolant configuration, custom geometry and order quantity. Final production scheduling is confirmed after the tool specification and application requirements are approved.
