Magnum 5PC 82 Degree 1 Hole Countersink Set (3801810)
Eliminating secondary burrs during the deburring process requires a specialized single-flute geometry that provides smooth, chatter-free operation. The Magnum 3801810 Countersink Set features a 5-piece assortment engineered with an 82-degree point angle, making it ideal for prepping holes for standard flat-head fasteners. These tools utilize a unique "1-hole" design that efficiently clears chips through the center of the bit, preventing material buildup and thermal stress in both ferrous and non-ferrous metals.

Frequently Asked Questions
Q: What materials can these countersinks be used on? A: The single-hole high-speed steel design works well on aluminum, brass, mild steel, and plastics.
Q: Why choose a 1-hole design over a fluted countersink? A: A single-hole geometry pushes chips through the center, significantly reducing chatter and leaving a smoother finish on the countersunk rim.
