What this step drill bit does
The IVY Classic 9002 step drill bit creates six fractional hole sizes from 3/16 to 1/2 inch in a single tool. It is designed for electricians, auto mechanics, sheet metal workers and general contractors who need quick, accurate holes in metal, wood or plastic up to 3/8 inch thick.
How the design features change the job
A Sure-Start point centres the bit instantly and prevents walking on smooth surfaces. Precision-ground molybdenum steel resists heat and abrasion for longer life. Lobular shanks grip the chuck without slipping. Laser-marked sizes let you stop at the right diameter without guesswork. The conical shape eliminates flex while drilling.
Installing and using the bit
The 1/4 inch shank fits standard drill chucks and locks securely thanks to the lobular flats. No special adapters or pilot holes are required. The bit can wander if side pressure is applied before the Sure-Start point engages, so start the drill straight and let the tip self-centre. Overheating shortens edge life; use cutting fluid on metal and clear chips often.

Questions about this item
Will the cutting edges on the 9002 step drill bit need resharpening, and how often?
The molybdenum steel construction resists wear from heat and abrasion, extending edge life; resharpening is rarely needed for typical sheet-metal work up to 3/8" thick.
What stops me from drilling deeper than 3/8" in a single pass with this bit?
The stepped cone geometry is designed for material up to 3/8" thick; beyond that the hole depth exceeds the step length and burr-free results are not guaranteed.
Does the 1/4" lobular shank run cooler or draw less power than a round shank during all-day use?
The lobular shank prevents slip in the chuck, maintaining consistent torque transfer; heat and power draw depend on the drill motor and feed rate, not the shank shape.
