PROMATOOL carbide drills: general characteristics
Carbide drills are made of fine-grained hard alloy with wear-resistant coatings providing:
|
- increased wear resistance;
- stability of the geometry of the cutting part;
- high precision of the resulting holes;
- efficient chip formation.
Scope of application
The drills are designed for drilling:
- carbon and alloy steels;
- stainless and heat-resistant alloys;
- cast iron (of all types);
- titanium and aluminum alloys;
- composite materials.
Suitable for:
- drilling through and blind holes;
- re-drilling (increasing the diameter of existing holes);
- drilling (forming indentations).
PROMATOOL carbide drill bit with coolant supply
Innovative carbide drills designed for high-speed and deep drilling in the most difficult materials. The integrated coolant supply system directly to the cutting edge provides unprecedented cooling, efficient chip removal and a significant increase in tool durability.
Main advantages and features
- The highest cooling efficiency: The central channel for high-pressure coolant supply allows heat to be removed directly from the cutting area. This prevents overheating of the tool and the workpiece, which is especially critical when working with heat-resistant alloys, stainless steels and viscous materials.
- Unobstructed chip removal: The coolant flow washes the chips out of the drilling area even at great depths. This eliminates chip jamming, reduces vibrations and prevents drill breakage, ensuring consistently high processing quality.
- Increased durability: The combination of a solid carbide rod (monolith) and efficient cooling significantly reduces tool wear. The drill bit retains the sharpness of the cutting edges longer, which reduces the cost of frequent re-sharpening and replacement.
- High performance: The design allows you to work at increased cutting speeds and feeds, reducing machine time and increasing overall process productivity.
- Precision geometry: Optimized spiral grooves and sharpening angles ensure precise centering, excellent surface quality of the machined hole, and minimal dimensional deviations.
- Wide range of applications: Ideal for CNC machines, machining centers and machine tools equipped with a pressurized coolant supply system.
Scope of application
- deep and batch drilling;
- processing of hard-to-process materials: stainless and heat-resistant steels, titanium and nickel alloys;
- High-speed production in the automotive, aerospace and energy industries;
- internal thread application and subsequent operations requiring high hole precision.
PROMATOOL carbide drill without coolant supply
Reliable and productive carbide drills designed for universal use on any equipment. Thanks to their advanced geometry and high-quality hard alloy, they show excellent results even when working without applying coolant through the tool, making them the ideal choice for most everyday tasks.
Main advantages and features
- Versatility and flexibility: They are designed to work on any type of machine tools – from universal drilling machines to modern CNC machining centers. They work effectively both with external cooling (emulsion, oil) and in conditions of minimal cooling.
- Optimized geometry of the chip grooves: The special profile of the grooves ensures effective chip formation and removal, preventing it from clogging in the grooves and reducing the load on the tool.
- Increased durability and vibration resistance: The robust construction and one-piece carbide rod ensure high rigidity, which minimizes runout and vibration, ensuring a precise and clean opening.
- Long service life: High-quality hard alloy has excellent wear resistance, which ensures long-term operation without loss of cutting properties and reduces the cost of processing.
- Excellent surface quality: The sharp cutting edge and precise sharpening make it possible to produce holes with high surface quality, often eliminating the need for subsequent refinement (for example, deployment).
- Economic efficiency: They are the optimal price/performance solution for most standard drilling operations.
Scope of application
- drilling holes of small and medium depth in carbon and alloy steels, cast iron, non-ferrous metals and alloys;
- serial production on universal machines and in conditions where there is no coolant supply system through the spindle;
- repair shops, small-scale production, tool shops;
- processing of materials that do not require intensive cooling (for example, cast iron).
Why choose PROMATOOL drills
- Durability: multiple overflows without loss of performance.
- Accuracy: minimum runout, compliance with specified tolerances.
- Versatility: work with a wide range of materials.
- Productivity: high cutting speeds due to the properties of the hard alloy.
- Reliability: process stability without vibrations and deviations.
