High Temperature Alloy Carbide Drill Bits | 1-20mm 3XD 5XD Coolant Through

1. Product Introduction

The High Temperature Alloy Carbide Drill Bits | 1-20mm 3XD 5XD Coolant Through are designed for CNC drilling of difficult-to-machine materials, including nickel-based alloys, titanium alloys, and heat-resistant stainless steels. Manufactured from ultra-fine-grain solid carbide, these drills combine wear resistance, cutting-edge strength, and precision-ground geometry for demanding industrial machining operations.

Available in diameters from 1.0 mm to 20.0 mm, with 3XD and 5XD length options, the drills feature internal coolant holes to deliver coolant toward the cutting zone. This design helps manage cutting heat, support chip evacuation, and improve drilling stability, particularly when machining heat-resistant alloys and deeper holes.

With application-specific coatings, optimized cutting geometry, and standard or customized configurations, the series supports precision drilling in aerospace components, turbine parts, energy equipment, and other applications where material toughness and work hardening create machining challenges.

Changzhou Boston Tool Co., Ltd. manufactures precision cutting tools, including solid carbide drills, milling cutters, reamers, and customized special tools. Standard and non-standard tool requirements can be discussed according to workpiece material, hole dimensions, and production conditions.

2. Key Product Features and Advantages

Ultra-Fine-Grain Solid Carbide Substrate

The carbide substrate is designed to balance hardness, toughness, and wear resistance. These properties help the cutting edges withstand the demanding conditions associated with nickel-based alloys and titanium alloys. Actual tool performance depends on the workpiece grade, hardness, machine rigidity, and cutting parameters.

High-Temperature-Resistant Coating Options

The specified coating system is designed to improve oxidation resistance, reduce friction, and limit material adhesion at the cutting edge. Appropriate coating selection can help reduce built-up edge formation and wear when machining difficult-to-cut alloys.

Optimized Cutting-Edge Geometry

The point geometry and edge preparation are designed to balance cutting sharpness and edge strength. This helps manage cutting resistance and supports stable drilling in materials that may work-harden during machining.

Internal Coolant Hole Design

Internal coolant channels deliver coolant toward the cutting zone, helping remove heat and assist chip evacuation. The design is particularly relevant to deeper drilling operations, where heat accumulation and chip removal can affect tool life and hole quality.

3XD and 5XD Configurations

The available length options support different hole-depth requirements. A 3XD drill is intended for relatively shallower holes, while a 5XD configuration accommodates greater drilling depth relative to the tool diameter. Actual usable depth depends on the tool design and machining setup.

Precision Grinding and Dimensional Consistency

Precision CNC grinding helps maintain consistent tool geometry. The product information specifies H7-grade hole precision as a potential machining result, but the achieved hole tolerance depends on the machine, tool condition, workholding, material, and machining process.

Standard Sizes and Customization

The stated diameter range is 1.0–20.0 mm. Customized diameter, overall length, flute length, point angle, coating, and other specifications can be discussed for application-specific requirements.

6. Recommended Cutting Parameters

The following values are reproduced from the supplied preliminary cutting data. They should be treated as starting references, not guaranteed settings for every tool, machine, or alloy grade.

Drill Diameter (mm)	Titanium Alloy Speed (rpm)	Titanium Alloy Feed (mm/rev)	Inconel Speed (rpm)	Inconel Feed (mm/rev)
4	1500	0.04–0.06–0.08	1200	0.04–0.06–0.08
6	1060	0.05–0.08–0.10	780	0.05–0.08–0.10
8	750	0.06–0.09–0.11	600	0.06–0.09–0.11

Feed values are presented as minimum–recommended–maximum, in mm/rev.

The supplied general cutting-speed reference for titanium and Inconel alloys is 10–20–30 m/min. However, the table lists specific spindle speeds for selected diameters. Because spindle speed depends on tool diameter and cutting speed, confirm that the selected values are appropriate for the actual alloy grade and tool configuration before machining.

For diameters not listed, as well as other superalloy grades, request application-specific cutting data from the supplier.

7. Operating Recommendations

To improve drilling stability and help extend tool life, consider the following practices:

• Verify coolant delivery: Ensure that the internal coolant passages are compatible with the machine connection and that the coolant supply meets the tool's requirements.

• Use stable clamping: Secure the workpiece and tool properly to reduce vibration and positional deviation.

• Minimize tool overhang: Keep unsupported tool length as short as practical for the required hole depth.

• Control chip evacuation: Use a suitable drilling cycle for the material and depth. Peck drilling may be necessary when chip evacuation is difficult, subject to the tool manufacturer's guidance.

• Match cutting parameters to the alloy: Avoid applying general-purpose steel parameters to nickel-based or titanium alloys without verification.

• Monitor tool wear: Inspect the cutting edges and machined holes periodically, particularly during initial process validation.

• Confirm the coolant method: Use wet cutting or MQL only where compatible with the tool configuration and machining recommendations.

The optimal machining strategy depends on hole depth, alloy condition, coolant pressure, machine rigidity, and the required surface finish.

9. Frequently Asked Questions

Q1: Why are specialized carbide drills recommended for high-temperature alloys?

Nickel-based and other heat-resistant alloys can generate high cutting temperatures, resist deformation, and work-harden during machining. These conditions can accelerate tool wear and increase the risk of chipping or unstable drilling. A suitable carbide substrate, coating, and cutting geometry can help address these challenges.

Q2: Can these drills machine titanium and nickel-based alloys?

They are designed for applications involving titanium alloys, nickel-based alloys, and selected heat-resistant materials. Confirm the exact alloy grade, workpiece hardness, hole depth, and tool specification to establish suitable cutting parameters.

Q3: What is the advantage of internal coolant holes?

Internal coolant delivery directs coolant toward the cutting zone, helping manage heat and remove chips. It can be especially beneficial in deeper holes, where external coolant may not reach the cutting edge effectively. Performance depends on coolant pressure, flow, fluid selection, and tool design.

Q4: What is the difference between 3XD and 5XD?

The X designation expresses flute or drilling length relative to the nominal tool diameter. A 3XD option is generally intended for shallower holes, while 5XD supports greater depth. Confirm the manufacturer's definition of usable drilling depth and the recommended drilling cycle for the selected model.

Q5: What diameter sizes are available?

The stated diameter range is 1.0–20.0 mm. Standard availability and stock status should be confirmed at the time of inquiry. Non-standard dimensions may be considered subject to manufacturing feasibility.

Q6: Can I request a customized drill?

Yes, customization can be discussed for diameter, length, flute length, point geometry, coating, and other application requirements. Logo marking and special packaging should also be confirmed before order placement.

Q7: What is the MOQ and delivery time?

The supplied information lists a minimum order quantity of two pieces for standard sizes, estimated delivery of 3–5 working days for in-stock products, and 7–15 working days for customized products. These are indicative figures and require confirmation based on inventory, specifications, and order quantity.

Q8: How can I obtain the correct cutting parameters?

Provide the tool diameter, hole depth, workpiece alloy grade, material hardness, machine specifications, coolant arrangement, and required hole tolerance. The supplier can then help evaluate an appropriate tool configuration and preliminary cutting parameters.
