The M12 x 1.75 is the "backbone" size for structural bolting in construction, automotive frames, and heavy machinery. Our DIN 352 Hand Tap Set is designed to solve the primary challenge of M12 tapping: High Radial Torque. By distributing the cutting load across a 3-piece sequence—Taper, Plug, and Bottoming—we ensure that threads are formed with 100% vertical alignment and zero micro-cracking in the workpiece, which is vital for load-bearing fasteners.

Most M12 taps fail due to "edge chipping" during the transition from the Taper to the Plug tap. Our HSS-M2 series features Optimized Flute Geometry that provides 20% more chip evacuation space than standard designs. Every tap is Fully Ground from a solid hardened blank, ensuring that the cutting edges are not just sharp, but metallurgically stable. This prevents the surface decarburization common in cheaper "rolled" or "half-ground" taps, leading to a tool life that consistently outperforms competitors in high-tensile steel (up to 900 N/mm²).
• Automotive Chassis & Suspension: Ideal for cleaning or creating critical threads in subframes and control arm mounts where M12 fasteners must meet strict safety tolerances.
• Heavy Plant Maintenance: The preferred choice for on-site repair of hydraulic brackets and gearbox housings where machine access is restricted.
• Structural Steel Fabrication: Designed to handle the abrasive nature of gray cast iron and structural steel plates used in bridge and building construction.
• Blind Hole Perfection: The No.3 Bottoming tap allows for threads to reach the absolute maximum depth, ensuring that M12 bolts have the full 1.75mm pitch engagement for maximum vibration resistance.
We understand that for global distributors, "Product Protection = Brand Protection." Each 3-piece set is housed in a shockproof Rose-Box plastic case and dipped in a proprietary high-viscosity anti-rust oil. This ensures that the delicate cutting edges remain "factory-sharp" even after 6 months of sea transit. Since 1997, we have provided full OEM support, including laser-marking your brand logo on the 9.0mm shanks and providing customized SKU labels for seamless automated inventory management.
Q:What is the "Total Cost of Ownership" advantage?
A:While M2 steel has a higher initial cost than 4341, it provides 3x to 5x the tool life. For your industrial clients, this means fewer tool changes and a lower "cost-per-hole," making your brand the preferred choice for professional users.
Q:What is the precise drill size for M12 x 1.75?
A:For a perfect 6H fit, a10.2 mm tapping drill bit is required. Using a 10.0mm bit will drastically increase torque and the risk of tap breakage, while a 10.5mm bit will result in weak threads.
Q:Can you support custom thread lengths for specific MRO projects?
A:Yes. As a factory-direct supplier, we can customize thread lengths or shank dimensions for large-volume wholesale orders to meet specific local market engineering standards.
