The Draper HSS Titanium Nitride Coated Drill Bit (7.0mm x 109mm) is an ideal choice for metalworkers and DIY enthusiasts who require a durable, precise tool for drilling into steel, non-ferrous metals, wood, and hard plastics. Its titanium nitride coating offers significantly enhanced strength and longevity compared to standard bits, though it performs most effectively when used in tandem with a cooling agent to prevent overheating.

No, this is a high-speed steel bit designed for metal, wood, and plastic. It will become blunt immediately if used on masonry or concrete.
Yes, it is compatible with standard 10mm and 13mm drill chucks found on almost all consumer-grade cordless drills.
The coating acts as a protective layer that increases the hardness of the bit and reduces friction, leading to faster cutting and a longer tool life.
The 135-degree split point is designed to prevent the drill from sliding or 'walking' across the material surface, allowing for a precise starting point.
While the titanium coating is durable, all HSS bits will eventually dull with heavy use. It can be sharpened using a standard drill bit sharpener.
Ensure you are using the correct downward pressure and that the split point is properly engaged. If the surface is exceptionally smooth, consider using a center punch to create a small dimple first.
Reduce your drilling speed and increase the use of cutting oil or a cooling agent to dissipate heat effectively.
Ensure you are clearing the flutes of debris frequently and check that your drill is set to the correct rotation direction.
To install, open your drill's chuck until the jaws are wide enough to accommodate the shank of the bit. Insert the bit fully and tighten the chuck securely to ensure it is centered. This bit is compatible with any standard corded or cordless drill featuring a 10mm or 13mm chuck. To maintain the life of the tool, store it in a dry, organized case to prevent oxidation. After use in wood or plastic, wipe clean with a soft cloth. If the bit becomes dull, it can be sharpened using a specialized drill bit grinding tool, though take care to maintain the original 135-degree angle to preserve the split-point functionality.
