{"product_id":"drill-stop-20","title":"Drill Stop #20 - Spring Loaded Depth Stop for Sheet Metal Drilling, Zinc","description":"\u003cp\u003eThis drill stop fits #20 drill bits (0.161\" \/ 4.09 mm). #20 is the specified drill for 5\/32\" blind rivets, including CherryMAX -5 and 5\/32\" pop rivets, which call for a 0.160\" to 0.164\" hole. It is also the larger of the two accepted drills for 5\/32\" solid rivets (the other is #21), and 5\/32\" clecos fit either hole. The spring is zinc (silver).\u003c\/p\u003e\u003cp\u003eA drill stop is a spring loaded depth stop that locks onto the shank of the bit with a hex socket set screw. Only the length of drill you leave exposed can enter the work, so the bit cannot go any deeper than you set it. As you reach depth, the rounded steel nose settles on the panel and the coil spring takes the lunge out of the breakthrough, instead of letting the chuck slam into the skin.\u003c\/p\u003e\u003cp\u003eBlind rivets go where you cannot reach the back of the job, which is exactly where you least want a bit running on into something you cannot see. Set the stop for the stack you are drilling and the bit cannot go any further, and the spring soaks up the breakthrough so the chuck never reaches the surface.\u003c\/p\u003e\u003cp\u003eDrilling 5\/32\" solid rivet holes with a #21?
