DrillSteady is a compact, portable drill jig that swings open to clamp on to your tubing. All you do is drill.

DrillSteady is easy to use, so it’s great for DIY and professionals who want to build a bimini top, boat dodger, add grab rails and more. It fits in your palm (or in your pocket), so it’s always close at hand.

Sound too good to be true?

With the DrillSteady drill guide:

  • You can drill a bent frame corner, stanchion or other tubing in place. There is no need to disassemble or remove tubing from your boat. This will save you time and money on cutting and welding (or repairing drilling mistakes)
  • A 9/64″ (3.5mm) drill bit is held in place securely (use #8 screws)
  • Large, knurled thumbscrews mean an easy grip and tight fit on tubing with diameter 3/4″ – 1 1/4″ (19.05mm – 31.75mm)
  • The durable cast metal drill guide body (zinc for DrillSteady, bronze for DrillSteady PRO) will not mar your shining stainless steel
  • The sturdy, tool steel drill bushing will give you years of service
  • Invented and made right here in Maine

Our *NEW* DrillSteady PRO has all the features of DrillSteady, but with a even tougher cast bronze body. Great for heavy use, we’re so sure DrillSteady PRO will keep up with you that we’ll replace it if it ever breaks under normal use. Just send us back the broken parts, tell us what you were drilling when it broke, and we’ll send you a new one.

Drill Steady Pro

Great piece of kit, worked as described. Great for initial hole drilling and also as a pilot hole for a larger bit if a bigger hole is required.

How big a drill bit can I use?

can I use a 1/4″ dia bit?


Response from Gemini Marine Products

Thank you so much for the review. To answer your question, the DrillSteady is designed to take a 9/64 drill bit. If you need something larger, we recommend you use this as your guide hole. All the best and good luck!
