Extra-Length Drill Bit Set
The Drill America five-piece set supplies high-speed-steel bits with an overall length of 12 inches. The extended reach suits maintenance and fabrication tasks where standard bits cannot access the workpiece. Sizes run from 1/4 inch to 1/2 inch to cover common fastener diameters. The set targets mechanics and fabricators who need deeper drilling without changing tools.
Transparent Case and HSS Construction
A transparent case lets the user confirm bit selection at a glance and keeps the bits organised during transport. High-speed steel withstands the heat generated when drilling iron and steel families of material. The straight shank fits standard drill chucks so the bits work with handheld or bench-mounted drills. No surface coating is mentioned in the supplied data.
Five Sizes in One Package
The bundle delivers 1/4, 5/16, 3/8, 7/17 and 1/2 inch bits in a single case, reducing the need to purchase individual bits for each job. Having the full range on hand speeds up workflow when hole diameters vary across a project. California Proposition 65 notices advise that the product contains chemicals known to cause cancer and reproductive harm.

Questions about this item
What shank size do the 1/4" to 1/2" drill bits use for a standard drill chuck?
Each bit has a straight round shank that matches its cutting diameter, so the 1/2" bit needs a 1/2" capacity chuck while the 1/4" bit fits any 1/4" or larger chuck.
What clearance is required to fit the 12" overall length bits into a workpiece?
You need at least 12" of straight-line access from the chuck face to the hole location, plus room for the drill body and your hand to operate without obstruction.
How are the five bits secured in the transparent case for storage and transport?
The case has individual moulded slots that snap each bit in place by its shank; press each bit firmly until it clicks so the bits cannot rattle loose during movement.
