BAER UNiTap HSSE-TiAlN Machine Tap 40° RSP – M 8 x 1.25 – DIN 371

UNiTap – Universal High-Performance Machine Tap for All Materials and Applications

One Tap. Every Thread. Unlimited Efficiency.

Take your threading operations to the next level with UNiTap, the universal machine tap trusted by professionals in workshops and industrial production worldwide. Engineered in Germany by BAER, the UNiTap offers unmatched precision, durability, and versatility—cutting perfect threads in a single operation across virtually all materials.

Designed for CNC machines, tapping arms, cordless drills, and threading machines, the UNiTap replaces multiple tools, reduces setup time, and significantly lowers production costs—making it the #1 choice for both high-volume series production and flexible machining environments.

Why Choose UNiTap?

• ✅ One Tap for All Materials: Easily cuts threads in steel, stainless steel, aluminum, copper, and high-temperature alloys

• ✅ Single-Step Threading: Machine thread in one efficient pass—no pre-drilling or secondary finishing required

• ✅ Perfect for Blind Holes: Spiral flutes and short chamfer ensure reliable chip evacuation

• ✅ DIN 371 Reinforced Shank: Delivers superior stability and vibration resistance

• ✅ TiAlN Coated: Withstands extreme heat and friction; ideal for dry machining and deep holes

• ✅ HSSE Cobalt Alloy: Extreme toughness and long tool life—even under demanding conditions

• ✅ Up to 5x Recoatable: Extend tool life with recoating options without removing the base layer

Built for Precision, Made to Last

UNiTap’s specially ground geometry ensures smooth chip flow, gauge-accurate threads, and a superior finish—on any material. Its advanced TiAlN coating allows higher cutting speeds (>60 m/min) and outstanding performance with minimal cooling—making it perfect for automated CNC production, job shops, and workshops with changing requirements.

Unlike standard taps, the UNiTap is optimized for performance under all conditions—from mass production to custom threading tasks—with zero compromises on quality or efficiency.

Reduce Costs. Increase Output. Maximize ROI.

Forget changing tools for every material. With UNiTap, you save time, reduce tooling costs, and increase uptime—all with one universal threading tool.
