Product details
If you are serious about off-roading, then you need a JKS step drill bit for drilling and enlarging holes to accept heavy-duty hardware. The 1699 Step Drill Bit will drill holes from 3/16 inch to 7/8 inch in 1/16 inch increments.
Thanks to the self-piloting design, you only need a center punch to locate your hole. Made from hardened high-speed steel with a titanium nitride coating and a heavy-duty 3/8 inch shank. The dual-flute design provide fast, smooth cutting.
Works well as a deburring tool too. One unique application where we have found ourselves using these bits is to drill out JK knuckle steering arms to accept JSPEC drag link flip.
