19/64 in x 18 in High Speed Steel Extra Long Drill Bit - Extra Reach

In this review the Drill America 19/64 in x 18 in High Speed Steel Extra Long Drill Bit is judged as a practical, low-cost option for jobs that need extra reach. The bottom line: it is best for maintenance work, production drilling, and home shops that encounter thick stacks or hard-to-reach holes where a standard-length bit will not reach. The single biggest reason to buy is the long flute length that delivers reach while retaining the toughness of high-speed steel for use in many iron and steel family materials.

Key Features

• Extra length: The 18 in length gives extended reach for drilling through assemblies or deep blind holes that standard bits cannot access.
• High-speed steel construction: Provides a balance of hardness and toughness for wear resistance across a broad range of steel and iron work.
• Black oxide treatment: Adds lubricity and helps retain coolant near the cutting edge to improve performance and reduce heat buildup.
• Spiral flute design: Right-hand spiral flutes evacuate chips up and out of the cut to lower the chance of clogging on long cuts.
• Round shank: Fits many toolholding systems so it can be used in drill chucks and other holders without special adapters.

Who It's For

The bit is aimed at tradespeople and maintenance technicians who need extra reach for drilling into stacked materials, repair work, or fixtures where the drill body cannot get close to the work. It also suits small production runs where a dependable, general-purpose long drill is needed without a premium specialty tool.

Those who should look elsewhere include users who need long-life performance in abrasive materials or very high-speed production - specialized coated or carbide long drills will outlast a plain HSS tool in those cases. Also, for precision or CNC work that demands ultra-tight tolerances and consistent edge geometry, a ground or specialty bit may be a better choice.

Pros & Cons

Pros

• Good reach for deep holes while maintaining the toughness of high-speed steel.
• Black oxide finish helps reduce friction and keeps coolant near the cutting edge for longer cuts.
• Round shank and spiral flutes make chip evacuation and toolholding versatile for shop and field use.

Cons

• Mixed reports on durability and initial sharpness mean some users may see shorter life compared with coated or premium bits.

Our Verdict

For anyone who needs extra reach without buying a specialty long-life tool, this 19/64 in x 18 in HSS extra long drill bit is a sensible value: it combines useful length, chip evacuation, and the workability of high-speed steel for common iron and steel tasks. Buy it for maintenance, light production, and shop projects - but consider coated or carbide alternatives for abrasive materials or higher-production longevity.

Frequently Asked Questions

Is this bit suitable for steel?
Yes. It is designed for general purpose drilling in a broad range of materials in the iron and steel families.

Will it fit my drill?
The round shank works in most chucks and common toolholding systems, but verify chuck capacity before purchase.

Does the black oxide make it long lasting?
The black oxide adds lubricity and helps retain coolant, which improves cutting performance, but it is not a substitute for specialty coatings in heavy production.
