Drills create cylindrical holes in workpieces, while taps create internal threads for fasteners like screws or bolts.
Drills come in types such as twist drills and spade drills, while taps include spiral point, spiral flute, and straight taps for different threading applications.
Coatings like TiN or TiAlN are applied to both drills and taps to improve wear resistance, reduce friction, and extend tool life.
Drills provide precise hole sizes and finishes, while taps ensure high-precision threading with smooth internal surfaces, ideal for tight-tolerance applications.
Drills and taps are often used together in machining, where a hole is drilled and then tapped to create threads for assembling parts.
YG-1 CENTER DRILLS
Center Drills
Center drills are used to create a small, accurate hole at the center of a workpiece, providing a starting point for larger drills or turning operations.
They have a pointed tip and a unique design that creates a conical shape to ensure proper alignment when starting a hole.
Center drills come in single-ended and double-ended types, with double-ended drills allowing for both a pilot hole and center hole in one tool.
Made from high-speed steel (HSS) or carbide, center drills offer durability and wear resistance for machining a wide range of materials.
Center drills are mainly used in turning operations to create accurate starting points for lathe work or to set up workpieces for center mounting.
HSS Drills
HSS (High-Speed Steel) end mills are made from high-carbon steel alloys that maintain hardness and performance at elevated cutting speeds.
They are used in milling machines to remove material from a workpiece, excelling in operations like slotting, contouring, and side milling.
HSS end mills are ideal for moderate-speed cutting and are effective for machining softer metals like aluminum, brass, and mild steel.
Available in various designs such as square end, ball nose, and corner radius, HSS end mills are used for both roughing and finishing operations.
HSS end mills are cost-effective compared to carbide tools, making them an affordable choice for general-purpose or less demanding machining tasks.
