Professional TiAlN Coated Countersink Set (1/4" - 3/4") – Extreme Wear & Heat Resistance
Description:
Achieve flawless, chatter-free countersinks in hardened steel, stainless steel, and alloyed materials with this professional-grade set. The advanced TiAlN (Titanium Aluminum Nitride) coating provides a super-hard, heat-resistant surface that lasts up to 5x longer than standard HSS countersinks. The set includes six industry-standard sizes (1/4", 5/16", 3/8", 1/2", 5/8", 3/4") with a versatile 82° included angle for common flat-head screws. Perfect for machine shops, fabrication, and serious DIYers who demand precision and durability.
Key Features:
TiAlN Nano-Coating: Superior lubricity and extreme heat resistance reduce friction and prevent built-up edge.
Longest Tool Life: Ideal for abrasive and hard materials. Outlasts nitrided and TiN-coated tools.
6-Piece Set: Covers sizes 1/4", 5/16", 3/8", 1/2", 5/8", 3/4" (82° angle).
Reduced Chatter: Precision-ground flutes ensure smooth, vibration-free operation.
Universal Shank: 3/8" shank fits most hand drills, drill presses, and CNC collets.
Option 2: Detailed & Technical (Ideal for Industrial/Machine Shop Buyers)
Headline: High-Performance 6-Piece TiAlN Coated Countersink Set | 82° | 1/4" - 3/4" Sizes
Description:
Engineered for the most demanding applications, this countersink set features a state-of-the-art TiAlN (Titanium Aluminum Nitride) PVD coating. This multilayer coating exhibits extreme surface hardness (≈85 HRC) and outstanding thermal stability (up to 800°C), making it the premier choice for machining tough materials like stainless steels, Inconel, titanium, and tool steels.
The precisely ground 82° included angle matches ANSI standard flat-head screws, producing clean, accurate chamfers and deburring edges. The robust design minimizes deflection and chatter, even at higher speeds, ensuring a superior finish every time.
