Tooling for Every Aerospace Operation
The right cutting tool for titanium, aluminium alloys, Inconel and CFRP — all available in stock for next-day delivery.
Thread Milling
Solid carbide thread mills for titanium, Inconel and aluminium. Ideal for aerospace blind holes, boss features and structural fastener threads. Single-point entry, no tap breakage.
Shop Thread Milling →Carbide Drilling
Through-coolant carbide drills for drilling titanium and Inconel at high feed rates. Excellent chip evacuation, reduced thermal load, consistent hole geometry across the batch.
Shop Carbide Drills →Solid Carbide Milling
End mills, chamfer mills and slot drills in carbide grades suited to titanium and high-temperature alloys. Sub-micron substrate for extended tool life under demanding aerospace cuts.
Shop Milling →Precision Turning
Turning inserts, boring bars and parting tools for aerospace components. Carbide grades and coatings matched to titanium, aluminium alloys, hardened steels and nickel alloys.
Shop Turning Tools →Deburring
Hand deburring tools, zero-flute deburring cutters and carbide burrs for finishing aerospace parts. Critical for edge preparation on flight-critical components before surface treatment.
Shop Deburring →Precision Toolholding
BT, HSK and DIN69871 spindle tooling with high-accuracy collet chucks. Hydraulic and heat-shrink holders for runout-critical aerospace machining centres.
Shop Toolholding →Precision Measurement
Calipers, micrometers, bore gauges and thread gauges for first-article and in-process inspection. Suitable for aerospace quality control procedures and CMM styli requirements.
Shop Measuring Tools →Thread Repair
Wire thread inserts and thread repair kits for repairing stripped or damaged threads in aluminium castings and structural assemblies — without scrapping the component.
Shop Thread Repair →When there's no margin for error, the tooling has to be right
Aerospace machining is about as unforgiving as it gets. Tight tolerances, difficult materials, strict traceability requirements and zero tolerance for scrap. The wrong cutting tool doesn't just cost money — on flight-critical parts, it can ground an aircraft.
Titanium, Inconel 718, 7075 aluminium, CFRP — each material demands a specific cutting geometry, grade and coating. A tool that works brilliantly on stainless steel will work terribly on titanium.
We stock cutting tools from brands including Carmex, OSG, Palbit and Widin — all selected for performance in difficult aerospace materials. Our applications team can help you match the right tool to your specific job.
Common Aerospace Machining Challenges
-
Heat in titanium and nickel alloys
Ti and Inconel are poor conductors — heat stays in the cutting zone. Through-coolant tooling and correct cutting data are essential to avoid built-up edge and premature failure.
-
Sub-±0.01mm tolerances
Aerospace components routinely require tolerances that demand ultra-precise toolholding, consistent tool geometry and rigorous first-article verification.
-
Threaded features in difficult materials
Tapping titanium is risky — tap breakage is expensive and scraps the part. Thread milling eliminates that risk entirely and allows rework if the thread isn't right first time.
-
Traceability and batch consistency
Aerospace requires documented tooling and batch consistency. We can supply the same tool geometry, grade and coating repeatedly — and our team can advise on tool life data.
Aerospace Materials We Have Tools For
We stock cutting tools with the right substrate, geometry and coating for every aerospace workpiece material.

Precision Cutting Tools for Aerospace Machining — Protool Ltd
Protool supplies cutting tools for aerospace manufacturers across the UK, including carbide drills, thread mills, solid carbide end mills, turning inserts and toolholding for machining titanium, Inconel, aluminium alloys and other aerospace-grade materials.
Aerospace machining places exceptional demands on cutting tools. Titanium alloys such as Ti6Al4V generate high cutting temperatures and are prone to work hardening — requiring specific carbide grades with PVD coatings, through-coolant capability and conservative cutting data. Nickel superalloys such as Inconel 718 are notoriously difficult to machine, with high strength at elevated temperatures and a tendency to cause built-up edge on the cutting face. CFRP machining requires diamond-coated or specialist geometry tools to prevent delamination. Our team can help you select the correct tool for every aerospace material and operation.
Thread Milling for Aerospace Fastener Features
Thread milling is the preferred threading method for aerospace components machined in titanium and nickel alloys. Unlike tapping, thread milling uses a rotating cutter to interpolate the thread profile — eliminating the risk of tap breakage in the workpiece. A single solid carbide thread mill can produce any thread diameter, allowing rework if the thread profile needs adjusting. Carmex thread mills, available from Protool, cover all standard aerospace thread profiles including ISO Metric, Unified (UNC/UNF), BSP, NPT and NPTF.
Drilling Titanium and Inconel for Aerospace
Through-coolant solid carbide drills are the standard for drilling titanium and Inconel in aerospace applications. The coolant delivered directly to the cutting edge reduces thermal load, improves chip evacuation and significantly extends tool life compared to standard drills. Protool stocks solid carbide through-coolant drills in a wide range of diameters for aerospace hole-making operations, with same-day dispatch for orders placed before 4:30pm.
Precision Toolholding for Aerospace Machining Centres
Achieving aerospace tolerances requires not just the right cutting tool but the right toolholder. We stock BT, HSK and DIN69871 spindle tooling, ER precision collet chucks, hydraulic holders and heat-shrink toolholders from leading manufacturers. Reduced runout and vibration directly improves surface finish and dimensional accuracy on flight-critical components.
