STARRETT 185 Tap And Drill Gauge, 1 to 60 Inch Range, Tool Steel, 5/64 Inch Thickness

Starrett 185 drill gauge is used in metalworking and machining tasks. It accurately measures drill bit sizes, aiding in precise hole creation. Machinists and workers use this gauge to determine drill diameters, ensuring compatibility with desired fasteners or components.

Working Mechanism:

• This drill gauge comprises a set of stepped, concentric rings, each possessing a specific diameter increase.
• To utilise the gauge, place the drill bit into the appropriate ring that provides a snug fit without force or wobbling.
• Then note the diameter measurement indicated by the ring. This measurement corresponds to the diameter of the drill bit being assessed.
• The gauge's methodology rests on the reliable alignment of the chosen ring's edges with the drill bit's edges to ensure an accurate measurement.

Features:

• Starrett 185 drill gauge features steel construction with black oxide finish for longevity and rigidity.
• It is equipped with 60 labelled holes, each representing standard drill sizes ranging from 17 AWG to 3 AWG.
• This compact drill gauge has 6-1/4 inch length for ease of handling and storage.
• It offers fractional inch measurements, enhancing precision & accuracy.

Frequently Asked Questions:

Q. How do I choose the right drill bit size using a drill gauge?

A. Choose the hole on the gauge that matches the desired hole size. The corresponding drill bit that fits into the hole is the right size.

Q. How should I store and maintain a drill gauge to ensure its accuracy?

A. Store the gauge in a dry and clean place to prevent rust. Regular cleaning and avoiding impacts maintain accuracy.

Q. Can a drill gauge prevent drill bit breakage?

A. Yes, using the correct drill bit size recommended by a drill gauge can reduce the risk of breakage.
