Tap - Star

Product catalog summary

Overview: The document discusses KORLOY's Tap-Star, a high-performance threading tap designed to boost productivity through enhanced tool life and machining efficiency. It features a high toughness HSS substrate, special chamfer edge treatment, and TiAlN coating for improved wear and oxidation resistance.

Specifications: Tap-Star is available in various types and sizes, including spiral, point, straight, and roll taps, with coatings like TiAlN, Nitride, and TiCN. It caters to different thread types and pitches, with options for oil grooves and chamfer lengths.

Features: The Tap-Star offers increased chipping resistance due to its robust substrate and chamfer edge treatment. Its flute shape optimizes chip evacuation, and the TiAlN coating enhances temperature oxidation resistance.

Performance: Tap-Star provides a 30% to 50% longer tool life compared to competitors, especially in alloy and pre-hardened steels. Recommended cutting conditions are specified for materials such as carbon steel, stainless steel, cast iron, and non-ferrous metals.

Applications: Suitable for a variety of materials, including low to high carbon steels, alloy steels, stainless steels, cast irons, and non-ferrous metals like copper and aluminum. It is also applicable for thermosetting and thermoplastic materials.

Code System: A detailed code system identifies the specific type, substrate, thread, pitch, oil groove, chamfer length, size, and surface treatment of each tap.

Line-up: The Tap-Star line-up includes various tap types and sizes, with detailed specifications such as thread diameter, pitch, usable length, and connection sizes.

Safety Precautions for Metal Cutting:

Protective Gear: Wear protective gloves and safety glasses to prevent injuries.
Tool Usage: Avoid inappropriate usage or excessive cutting conditions to prevent tool breakage.
Workpiece Stability: Ensure the workpiece is securely clamped during machining.
Tool Management: Manage tool changes properly to avoid breakage from overuse.
Chip Handling: Use safety covers and tools to handle chips safely.
Fire Prevention: Implement measures when using non-water soluble cutting oils to prevent fires.
High-Speed Machining: Use safety covers to prevent ejection of parts due to centrifugal force.
