SPIRAL TAPS METRIC SUTTONSutton Tools metric spiral flute taps are high performance machine taps designed specifically for power tapping in blind holes, engineered to pull metal chips up and out of the hole to prevent tap breakage. Understanding the Technical Specifications M8 (Major Diameter): The tap creates a thread with a nominal outer diameter of exactly 8 millimeters. 1. 25 (Thread Pitch): The distance from the peak of one thread crest to the next is 1. 25 millimeters.
Sutton Tools metric spiral flute taps are high-performance machine taps designed specifically for power tapping in blind holes, engineered to pull metal chips up and out of the hole to prevent tap breakage.
Understanding the Technical Specifications
- M8 (Major Diameter): The tap creates a thread with a nominal outer diameter of exactly 8 millimeters.
- 1.25 (Thread Pitch): The distance from the peak of one thread crest to the next is 1.25 millimeters. This is the standard "Metric Coarse" pitch for an 8mm fastener.
- Spiral Flute (The Geometry): Instead of straight grooves, the flutes twist around the tool body like a drill bit. This helical design lifts metal chips up and out of the hole toward the entry point. It prevents chips from packing at the bottom, which is the leading cause of broken taps in blind holes.
Essential Operational Rules
- Pre-Drill Hole Size: You must pre-drill the hole using a 6.8 mm drill bit. Drilling a 7.0 mm hole will result in weak, shallow threads, while a 6.5 mm hole will bind and snap the tap.
- Lubrication: Never run a spiral flute tap dry. Use a dedicated cutting fluid or tapping paste (like Sutton's Tapping Fluid or Rocol) to reduce heat and friction.
- Machine Speed: Spiral flute taps are meant to run in a continuous forward motion. Avoid the "back-and-forth" hand-tapping method, as reversing prematurely can crush the delicate chips currently lifting up the spiral flutes

Perfect, it fits like a glove.
Color: 1-Navy Blue
I really liked the sleeve, the navy blue color looks very elegant and the material feels resistant but soft to the touch. What I like the most is that the back is translucent, so you still see the design of the tablet.
It works great for watching videos because it stands firm when folding it, and turning off the screen alone when closing it is very practical. Because of the price it has, the quality is excellent.

Great Protective Case for My Mother’s iPad
Color: 2-Watermelon Red, Color: 2-Watermelon Red
I bought this case along with my mother’s new iPad, and it was the perfect choice. The watermelon red color looks beautiful with the pink iPad and gives it a very clean and stylish look. The case feels sturdy without adding too much weight, which makes it comfortable for her to carry around and use every day.
The stand feature works really well for watching videos, reading, and video calls. I also like that the case supports the auto wake and sleep function, which makes the iPad feel even more convenient and easy to use. The cutouts fit perfectly, and Touch ID still works without any issues.
The translucent back is a nice touch because it still lets the iPad color show through while keeping it protected from scratches and bumps. Overall, this case exceeded expectations and makes a great addition for anyone wanting both protection and style for their iPad.

Good product. What you see is what you get.
Color: 1-Navy Blue
Material feels sturdy and was a perfect fit compatible for my iPad. There's adequate grip and padding for a comfortable yet slim feel. Magnets hold it close and in one position when propping it up for watching landscape videos. Back is translucent as advertised. Solid product, put it on as i opened my new ipad for immediate protection. Perfectly safe blind buy if you're also getting that 'frequently bought together' suggestion from Amazon.
