DRINYOUNG 3/8-16×130 Spiral Flute Thread Tap – Extra Long 130mm HSS Machine Tap, Right Hand, Blind Hole Compatible For Steel, Aluminum & Cast Iron

About This Product

When you're tapping deep holes, this DRINYOUNG spiral flute tap is exactly what you need.
It's a 3/8-16 UNC size with a 130mm (5.

12 inch) overall length and a 25.

5mm (1 inch) thread length.

The spiral flute design is a game-changer – chips evacuate upward and out of the hole as you cut, so they don't clog or jam.
That makes it especially good for blind holes, where chips getting stuck is a common problem.
Made from high-speed steel, so it's durable and holds an edge well.
Cuts smoother with less resistance than straight flutes.

Works on stainless steel, aluminum, alloy steel, cast iron, brass, and even hard plastics.
Use with a tapping machine, CNC, or bench drill – and always use cutting oil.
Great for machinists or serious DIYers who need precision threading in deep holes.
