99-piece titanium-plated straight-point twist drill bits, made of high-speed steel. The round handles are compatible with most electric drills. A wide range of specifications are available, allowing for drilling of wood, thin metals, and plastics. The spiral grooves facilitate chip removal. A hard plastic storage box is included for easy organization and carrying. Just open the box and start working.

It is recommended to control the feed speed during drilling operations to avoid excessive pressure that could cause the drill bit to overheat and become chipped. When processing metal materials, coolant can be used to cool down and extend the service life of the drill bit. Do not use it on materials beyond the applicable range such as hard alloys and thick quenched steel. Keep the storage environment dry to slow down oxidation and rusting. Replace the drill bit in time if it shows obvious wear or chipping. During operation, wear protective goggles properly and take safety precautions. When the drill bit is idle for a long time, clear the debris in the drill hole and store it in the toolbox.The complete set includes 99 different-sized straight-point twist drill bits, all stored in a hard tool box, with each section arranged for easy classification and retrieval. The drill bits are made of high-speed steel with a titanium coating on the surface, which enhances wear resistance and reduces wear on the cutting area. The uniform round handle design is compatible with most electric drills and rechargeable drill chuck heads. The specifications cover various commonly used sizes, meeting the needs of different hole drilling requirements. Once opened, the drill bits can be put into use immediately.
Applicable materials for processing
Suitable for drilling operations on common materials such as wood, plastic, thin aluminum sheets, and thin iron sheets. The spiral chip-removal groove design facilitates the discharge of chips during the processing, reducing the probability of drill bit jamming. The standard drill tip angle makes positioning easy, and marking the center before operation can reduce the initial slipping during drilling, making it suitable for home decoration construction, DIY, small-scale maintenance processing, etc.
Advantages of storage and portability
Complementary thick plastic tool box with a secure snap-lock closure, which is unlikely to loosen during transportation. The box is reserved with independent compartments, allowing drill bits to be classified and stored by specifications, reducing the loss of parts. The entire set is compact for storage and easy to carry to the construction site, workshop, or tool room. It is also suitable for unified storage in a tool room. Each drill bit is packaged independently and simply, reducing the scratches caused by mutual friction during storage.
Multiple usage scenarios
Suitable for home decoration woodworking drilling, hardware maintenance, model making, water and electricity installation, etc. Maintenance technicians, DIY enthusiasts, and construction workers can all use it. The rich specifications do not require separate purchases; a set of commonly used hole-drawing drill bits can be prepared at once, reducing the trouble of repeatedly selecting tools, and meeting the needs of both sporadic repairs and small-scale processing.
