What This Product Is and How It Works
The Prescott HSS Drill Bit 1 × 42 mm PTA101 is a twist drill bit manufactured from high‑speed steel (HSS). It removes material by shear cutting as the bit rotates and advances into the workpiece. The spiral flutes efficiently evacuate chips from the hole, reducing heat and facilitating continuous cutting action.
This bit is sized for drilling very small holes where precision and control are important, especially in detailed work and light fabrication tasks.
Material Quality, Durability and Environmental Performance
High‑speed steel maintains hardness at elevated temperatures generated during drilling, improving wear resistance and extending tool life compared with basic carbon steel bits. The small size and quality of the cutting edge make it suitable for controlled drilling in thin sheet materials and precision jobs.
Under typical Kenyan workshop conditions — including moderate humidity and airborne dust — the bit performs reliably when used with correct speeds and steady feed.
Installation, Handling and Compatibility
This drill bit fits into standard electric, cordless, or bench drills equipped with keyed or keyless chucks. Secure the bit fully in the chuck before operation to prevent slippage. For metal drilling, centre‑punch the drilling point to prevent wandering. Adjust drill speed appropriately: lower speeds for metals and higher speeds for wood or plastics.
Use eye protection and, where applicable for metal drilling, a light cutting fluid to control heat and improve chip evacuation.
Typical Applications in Kenya
This 1 mm drill bit is suited for precision drilling and light‑duty fabrication tasks. Typical applications include drilling pilot holes in thin metal panels, fine woodworking, electronics enclosures, and plastic components where a very small diameter hole is required.
It is commonly used by technicians, model makers, jewelers, electricians, and precision fabricators. For more drilling accessories and tools, customers can browse the full range in our Shop or explore the Power Tool Accessories Category.
