Before ordering
Compare the desired opening with the marked steps and verify the material thickness. Do not assume a uniform sequence from the endpoints and step count alone; the intermediate sizes are not itemized here. Match the holder and operating mode to the manufacturer's guidance, including any restrictions for the substrate.
Product questions and answers
Can it drill 1-1/8-inch-thick metal?
That is not the listed capacity. 1-1/8 inch is the maximum cutting diameter, while the listed metal-thickness limit is 5/32 inch.
Are all thirteen intermediate sizes specified here?
No. The range and step count are supplied, but not an itemized diameter list. Check the markings or manufacturer's size chart for a particular opening.
Is TiN the material of the whole bit?
No. TiN is a titanium nitride coating over the listed high-speed steel construction.
