Dormer E003 HSS-E High Perf Mult-App Metric Coarse Spiral Flute Tap

The Dormer E003 M12 Spiral Flute Tap delivers reliable performance for creating M12 metric coarse threads in blind holes, a popular size for heavy-duty fixings, machinery assembly, and structural applications. This robust tap is well-suited to both professional engineering environments and serious DIY projects requiring larger thread sizes.

M12 threads are frequently specified in automotive suspension components, industrial equipment mountings, and construction metalwork where stronger fixings are essential. The spiral flute geometry pulls chips upward and away from the cutting zone, which is particularly important in blind holes where chip accumulation can cause tap breakage or thread damage. The 3-flute configuration balances cutting efficiency with strength.

Manufactured from High Speed Steel Cobalt with a steam tempered finish, this tap maintains sharp cutting edges whilst the coating improves lubrication retention. The 16mm threading length accommodates most standard M12 applications, and the cylindrical shank with square drive provides positive engagement with manual tap wrenches or machine holders.

Features and Benefits:
• M12 thread size ideal for heavy-duty mechanical and structural applications
• Spiral flute design prevents chip accumulation in blind holes
• 16mm threading length suitable for standard fixing depths
• HSS-E cobalt material provides excellent wear resistance
• Steam tempered surface enhances cutting fluid performance
