Holesaw Arbor Set

Hole Saw Arbor Set — Aerospace-Grade 17-4 Stainless, Tight-Access, 4-Piece (with 1/4” & 1/8” Pilots)

Get your hole saw into places the factory never intended. This 4-piece set is built from heat-treated 17-4 stainless steel—the same alloy trusted in aerospace hardware—for maximum strength, wear resistance, and dimensional stability. These arbors are made for real sheet-metal work, not showroom benches.

What’s in the set

• 2 × Small-diameter arbors (3/8" Hole Saw bits) — 1/8" pilot
• One for threaded 90° angle drills
• One with a 1/4" shank for standard drill chucks
• 2 × Large-diameter arbors (1/2" Hole Saw bits) — 1/4" pilot
• One for threaded 90° angle drills
• One with a 1/4" shank for standard drill chucks
• Over-engineered carry case with dedicated slots for clean accessibility and positive tool control

Why you’ll like it

• Tight-access geometry: Short overall length to slip past ribs, bulkheads, and corners
• Aerospace-grade durability: Machined from 17-4 stainless steel—resists galling, distortion, and fatigue for a tool that outlasts mild-steel arbors.
• Clean, controlled cuts: Built for cutting perfect holes in aluminum—perfect for install work and field mods.
• Grab-and-go simplicity: Two sizes, two drive styles. The inhouse made case keeps your tools organized and ready to work.

Quick start — tight-access drilling

1. Pick your drill: Got enough clearance for your standard drill? Use the shank arbor. Need an angle head? Use the threaded 90° arbor.
2. Select your Hole Saw bit and arbor: For 5/16" to 7/8" holes, run the 3/8" arbors. Going larger than 7/8"? Grab the 1/2" arbors.
3. Drill the pilot:
• Using the 3/8" arbor? Drill a 1/8" (or #30) pilot.
• Using the 1/2" arbor? Drill a 1/4" pilot.
4. Cutting the hole: insert your Whiskey Victor arbor to your drill with the hole saw of choice and cut—steady feed, proper lube—for clean, perfect round holes in tight spaces. Don't forget the 2 included washers for a slip joint or it turns into a 1 time use tool!
