Drill America 1-1/16 in Reduced Shank HSS Drill Bit - Versatile Jobber

In this review the Drill America 1-1/16 in Reduced Shank High Speed Steel drill bit is judged as a practical, no-frills option for workshop and jobsite use; it is best for users who need a larger hole size from a portable drill chuck without upgrading chucks or machines. The biggest reason to buy is its reduced 1/2 in shank that lets a 1-1/16 in cutting diameter run in standard chucks, combined with HSS material and a black oxide finish that give reasonable wear resistance and chip control for low to medium tensile materials.

Key Features

• Reduced shank: the 1/2 in shank allows use in portable drill chucks so larger hole sizes are possible without special tooling.
• High speed steel construction: offers a balance of hardness and toughness for general purpose drilling in common metals and wood.
• 118 degree point grind: provides a reliable center and simpler starts on workpieces for cleaner holes with less walking.
• Black oxide finish: adds lubricity and creates small surface pockets that help hold coolant and reduce heat at the cutting edge.
• Spiral flutes: right-hand cut flutes evacuate chips up and out of the hole to reduce clogging and improve cutting action.
• Common flute and length: consistent dimensions simplify tool changes and maintain expected reach for jobber-style drilling tasks.

Who It's For

This drill bit suits hobbyists, fabricators, and contractors who occasionally need a 1-1/16 in hole but must use a portable drill or standard chuck; the reduced shank solves the compatibility issue without changing equipment. It is also sensible for small shops that perform low to medium tensile work such as mild steel, aluminum, and general carpentry.

Those who regularly drill hardened alloys, stainless steel, or run high-volume production cycles should look elsewhere toward coated or carbide options and higher wear-resistant geometries, since customers report mixed longevity and occasional rapid dulling under heavy use.

Pros & Cons

Pros

• Useful reduced 1/2 in shank makes large-diameter drilling feasible with standard chucks.
• HSS with black oxide offers good general-purpose performance and improved lubricity over bare steel.
• Spiral flutes and a 118 degree point produce acceptable hole quality and chip evacuation for common shop tasks.
• Affordable and straightforward choice for occasional large-hole needs.

Cons

• Some users report the edge dulls relatively quickly or chips on first use when pushed hard, so durability is mixed for heavy-duty work.
• Not intended for high-tensile or hardened materials where specialized coatings or carbide are required.

Our Verdict

The Drill America 1-1/16 in reduced shank HSS bit is a practical, value-oriented choice for users who need a large hole from a standard chuck and who work with low to medium tensile materials. It delivers acceptable hole quality and easier coolant retention thanks to the black oxide finish, but those needing high durability under heavy or hardened-material use should consider higher-grade alternatives.

Frequently Asked Questions

Can I use this bit in a handheld drill?
Yes, the 1/2 in reduced shank is designed to fit standard portable drill chucks so it can be used with handheld drills.

What materials is this drill bit best for?
It is best for low to medium tensile materials such as mild steel, aluminum, and general woodwork; it is not ideal for hardened steels or stainless without slower speeds and extra care.

Does the black oxide finish improve life?
The black oxide adds lubricity and helps hold coolant at the edge, which can improve cutting performance, but customers report mixed longevity depending on application intensity.
