40pcs metallic taps and die

A 40-piece metallic tap and die set is a more compact, but still very useful, version of a tap and die kit. It’s ideal for a range of common threading tasks, from repairing damaged threads on bolts and holes to creating new ones in various metallic materials.

What’s typically included in a 40-piece set:

While the exact sizes and types might vary slightly between manufacturers, a 40-piece set generally focuses on the most commonly used sizes, often in both metric and/or SAE (imperial) measurements. Here’s a typical breakdown:

• Taps (Internal Threads): You’ll find a selection of taps to cut internal threads in holes. This usually includes:
  • Taper Taps: For starting new threads.
  • Plug Taps: For cutting threads deeper.
  • A 40-piece set might include around 16-17 pairs of taps and dies, covering sizes like M3x0.5, M4x0.7, M5x0.8, M6x1.0, M8x1.25, M10x1.5, M12x1.75 for metric, and equivalent SAE sizes (e.g., 4-40 NC, 6-32 NC, 8-32 NC, 10-24 NC, 1/4-20 NC, 5/16-18 NC, 3/8-16 NC, 7/16-14 NC, 1/2-13 NC). Some sets may also include NPT (National Pipe Taper) sizes like 1/8″ NPT for pipe threads.
• Dies (External Threads): Corresponding dies for cutting external threads on rods or bolts. These often come in round or hexagonal shapes. You’ll typically find the same range of sizes as the taps.
• Wrenches and Holders:
  • Tap Wrenches: Usually an adjustable long-handle tap wrench and a T-handle tap wrench for smaller taps.
  • Die Holder/Wrench: To hold and turn the dies.
• Accessories:
  • Screw Pitch Gauge: Essential for identifying the thread pitch of existing threads.
  • Screwdriver: Often a small flat-head screwdriver for adjusting die holders or other components.
  • Storage Case: A durable case (often blow-molded plastic) to keep all the pieces organized and protected.
