A #2 to #4 drill sleeve would be used when...

• A. Fitting a #2 shank drill to a #4 spindle
• B. Aligning a drill with a hole
• C. Drilling larger holes
• D. Holding a larger drill in a chuck

Answer: (A)

Drill sleeves are used to adapt a drill’s shank size to the spindle size. A #2 to #4 sleeve provides a bore that accepts a #2 shank while its outer surface fits the #4 spindle. This lets you run a drill with a smaller shank in a spindle designed for a larger size without changing spindles or chucks. In operation, you place the sleeve in the spindle and insert the #2 shank drill into the sleeve, so the setup behaves like a proper drill for that spindle size. It’s not about aligning a drill with a hole, nor about drilling larger holes, nor about holding a larger drill—the sleeve’s job is to make the smaller shank fit the larger spindle.
