Key Features of Faithfull Cobalt Drill Bits

The cobalt alloy construction throughout the entire bit body provides exceptional hardness and heat resistance that outlasts surface-treated alternatives. This through-hardened composition means Faithfull cobalt bits can be resharpened multiple times without losing their cutting performance, offering excellent long-term value. The 135-degree split point geometry reduces the pressure required during drilling whilst preventing bit wander on curved or angled surfaces.

Faithfull incorporates precision ground flutes in their cobalt drill bits, ensuring efficient swarf evacuation even when drilling deep holes in tough materials. This design prevents chip clogging that can cause overheating and premature bit failure. The bits feature a bright finish that aids visibility during use and helps identify wear patterns, whilst the clearly etched size markings remain legible throughout the tool's working life.

The shank design on Faithfull cobalt drill bits ensures secure grip in standard drill chucks, minimising slippage during high-torque applications. Available in jobber length for general purpose drilling and longer series for deeper penetration requirements, the range at Tooled-Up provides comprehensive coverage for metalworking applications. Each bit undergoes individual inspection to ensure dimensional accuracy and concentricity, delivering the precision required for professional metalworking standards.

Popular Faithfull Cobalt Drill Bits

The Faithfull cobalt range encompasses individual drill bits in the most frequently specified sizes from 1mm through to 13mm diameter, covering the vast majority of metalworking drilling requirements. Single bits allow tradespeople to replace worn sizes without purchasing complete sets, offering economic flexibility for high-volume users. These individual bits are particularly popular with fabricators and engineers who wear through specific sizes more rapidly than others.

Faithfull cobalt drill bit sets provide comprehensive size ranges in organised storage cases, ideal for mobile tradespeople and workshop environments. These sets typically include metric sizing in 0.5mm increments through the smaller diameters and 1mm increments in larger sizes, ensuring the right bit is always available. The robust cases protect the bits during transport and storage, preventing damage to the precision-ground cutting edges.

Specialist configurations include extra-long series cobalt bits for deep hole drilling applications, and reduced shank versions that allow larger diameter bits to be used in standard 10mm or 13mm drill chucks. These specialist options extend the versatility of the Faithfull cobalt range to accommodate demanding fabrication and engineering challenges encountered in professional metalworking environments.

Safety and Compliance

When using Faithfull cobalt drill bits, appropriate personal protective equipment including safety glasses and gloves should always be worn to protect against sharp swarf and hot metal chips. The high cutting speeds achievable with cobalt bits generate significant heat, making cutting fluid or lubricant essential when drilling stainless steel and hardened materials. This reduces friction, extends bit life, and prevents work hardening of the material being drilled.

Secure workpiece clamping is critical when using cobalt drill bits, as their aggressive cutting action can cause rotation of improperly secured materials, creating dangerous situations. Always ensure the drill bit is properly seated and tightened in the chuck before commencing work. When drilling through materials, reduce feed pressure as the bit breaks through to prevent grabbing and potential injury.

Faithfull cobalt drill bits should be operated at the manufacturer's recommended speeds for the material being drilled. Excessive speed causes premature dulling and potential bit fracture, whilst insufficient speed can work-harden the material and prevent effective cutting. Regular inspection of bits for wear, damage, or cracks ensures safe operation and optimal performance throughout their working life.

Frequently Asked Questions

What's the difference between Faithfull cobalt drill bits and standard HSS bits?

Faithfull cobalt drill bits contain 5-8% cobalt alloyed throughout the entire bit structure, providing superior heat resistance and hardness compared to standard HSS bits. This allows them to maintain their cutting edge when drilling hard materials like stainless steel and cast iron, where standard HSS bits would quickly dull. Cobalt bits can operate at higher temperatures and last significantly longer when working with tough metals.

Can Faithfull cobalt drill bits be resharpened?

Yes, Faithfull cobalt drill bits can be resharpened multiple times whilst retaining their performance characteristics. Because the cobalt is alloyed throughout the bit rather than just surface-coated, resharpening doesn't remove the hardened material. When sharpening, maintain the original point angle and ensure even grinding to preserve the self-centring split point geometry that provides accurate drilling.

What materials are Faithfull cobalt drill bits suitable for drilling?

Faithfull cobalt drill bits excel at drilling stainless steel, cast iron, hardened steel, titanium, and other tough ferrous metals that quickly dull standard HSS bits. They're also effective for drilling softer materials like mild steel, aluminium, and brass, though their premium price makes them most economical for harder materials. They're the preferred choice whenever heat generation and material hardness challenges conventional drill bits.

Do I need a special drill to use Faithfull cobalt drill bits?

No, Faithfull cobalt drill bits work with standard power drills, pillar drills, and magnetic drilling machines that accept conventional parallel shank bits. However, for best results when drilling hard materials, use a drill with variable speed control and sufficient power to maintain steady rotation under load. Cordless drills should be fully charged, as cobalt bits require consistent torque for optimal cutting performance.

How should I store Faithfull cobalt drill bits to maintain their performance?

Store Faithfull cobalt drill bits in a dry environment, preferably in indexed cases or stands that prevent the bits from contacting each other and damaging their cutting edges. Keep them separated by size to make selection easier and avoid mixing them with standard HSS bits. Light coating with a corrosion inhibitor protects the bits during storage, and keeping them clean prevents built-up residue from affecting drilling accuracy.
