The Sealey AK3717TCM 17-piece drill bit set is an ideal starter kit for DIY enthusiasts and homeowners who require a versatile selection of bits for drilling through both metal and masonry. Combining titanium nitride coated high-speed steel (HSS) bits for durability with tungsten steel masonry bits for brickwork, this set provides essential coverage for standard household repairs, though it is not intended for heavy-duty industrial or professional construction use.

These bits use a standard cylindrical shank and will not fit directly into an SDS-plus or SDS-max chuck without an adapter.
While they can penetrate thin stainless steel, they are primarily designed for mild steel and general-purpose applications.
The coating increases the surface hardness of the bit and reduces friction, allowing for faster cutting and a longer lifespan.
Store them in the provided rubberized case in a cool, dry environment to prevent corrosion.
HSS bits can be resharpened with the correct grinding equipment, though masonry bits are significantly harder to sharpen due to their tungsten tips.
Ensure the drill chuck is fully tightened and that the bit shank is free of oil or grease.
Reduce the drill speed and use a cutting lubricant; ensure you are not applying excessive pressure.
Ensure the drill is set to 'hammer' mode if using a masonry bit, as rotary-only mode will be ineffective on harder brick.
To ensure the longevity of your Sealey AK3717TCM set, ensure the bit is fully seated and tightened within your drill chuck before starting. For metal drilling, the use of a cutting lubricant is advised to keep the TiN coating cool and effective. After use, wipe down the bits with a dry cloth to remove metal shards or dust before returning them to the case. This prevents rust buildup, especially on the non-coated portions of the tungsten masonry bits. The bits are compatible with all standard 3-jaw drill chucks found on most handheld power drills and drill presses.
