Model: SP8HH2 

Built tough and designed for precision, the Boss Hog Hole Hog Set is proudly manufactured in the USA from Super Premium Hi-Molybdenum High-Speed Tool Steel. Engineered to meet the rigorous standards of National Aerospace Standard 907, this set delivers exceptional performance when enlarging existing holes — without the snags, chatter, or catching common with standard drill bits.

Set Includes:

• Pilot Drills (3-Flat Shank, Made in USA):

  • 1/4″, 5/16″, 25/64″, and 15/32″

• Hole Hogs (4-Flute, 3-Flat Shank, Made in USA):

  • 3/8″, 1/2″, 5/8″, and 3/4″

Features:

• Made in the USA using Hi-Molybdenum High-Speed Steel for superior strength and durability

• 4-flute design minimizes catching and hogging-in, especially on thinner materials like truck frames

• Purpose-built for enlarging existing holes cleanly and efficiently

• Replaces tapered reamers in many applications

• Each Hole Hog can enlarge an existing hole by up to 60%

• Ideal for creating large diameter holes where the hole size exceeds twice the material thickness

• Reduces drill breakage, chipping, and bending compared to standard Silver & Deming bits

Applications:

1. Hole Enlargement: Paired pilot drills define the smallest starting hole size for each Hole Hog.

2. Thin Material Drilling: Perfect for large holes in thin or tough materials, eliminating the risks associated with conventional drills.

Important Safety Note:
Always use proper equipment and safety measures. Any cutting tool may break or shatter under improper use.
