The Faithfull Professional Long Series HSS Jobber Drill Bits (2.00mm) are essential tools for professional tradespeople and metalworkers who require precision drilling in deeper applications. Crafted from high-quality M2 grade steel, these bits provide excellent durability and heat resistance, though users should be mindful that their long design requires careful handling to prevent bending or snapping under high-torque conditions.

While designed for metals, they can be used on wood, but standard wood bits are usually more efficient for clearing chips in that material.
Yes, especially when drilling stainless steel or hardened alloys, as it significantly extends the life of the bit.
It is not recommended. Impact drivers apply shock loads that can easily snap long series drill bits.
M2 is a molybdenum-based high-speed steel known for its excellent toughness and ability to maintain hardness at high temperatures.
Yes, they are fully ground to DIN 338 standards, which dictates the tolerances and dimensions for jobber drill bits.
Ensure you are using the split-point center to engage the metal initially; if it persists, use a center punch to create a small dimple.
Reduce your drilling speed (RPM), increase pressure, and apply a dedicated metal-cutting fluid to dissipate heat.
Clear the hole frequently of metal shavings (peck drilling) to reduce friction and heat buildup along the shank.
To ensure the longevity of your Faithfull drill bits, always secure your workpiece with clamps to minimize vibration. These bits are compatible with standard corded and cordless drill chucks. When setting up, ensure the bit is properly seated in the chuck to prevent runout. After use, clean the bits of any metal shavings and apply a light coating of machine oil before storing them in a moisture-free environment to prevent oxidation. Avoid using these bits in hammer-drill mode, as the impact action will cause premature breakage.
