Drill America M22 x 2.5 Tap Set with 29.50mm HSS Black Oxide Drill — taper, plug, bottom taps, hand & machine use

This kit pairs a versatile set of M22 x 2.5 high‑speed steel taps (taper, plug, bottom) with a matching 29.50mm HSS black oxide drill bit. The taps accommodate hand or powered tapping and are suitable for general machine and CNC applications. The black oxide drill offers improved lubricity and chip control for common iron and steel family materials. Everything ships in a compact plastic pouch for toolroom or field use.

How does the tap set adapt to different hole types and starting conditions?

The set contains three tap profiles so you can start and complete threads in a variety of hole depths and entry conditions. The taper tap eases into the work, the plug tap is ideal for through holes, and the bottom tap finishes threads to the bottom of blind holes. This combination reduces the need to stock individual taps for each job.

• Taper tap: gentle thread entry for starting in difficult or square holes
• Plug tap: versatile choice for through‑hole threading
• Bottom tap: reaches full thread at the bottom of blind holes
• High‑speed steel construction for toughness across many materials

What advantages does the 29.50mm black oxide drill bit offer?

The Drill America 29.50mm HSS drill features a black oxide finish that increases surface lubricity and helps retain coolant at the cutting edge. That treatment also creates micro‑pockets that aid in chip evacuation and wear resistance. With a round shank and general‑purpose geometry, it fits common tool holders and works well for production, maintenance, and portable drilling tasks.

• Black oxide finish: better lubrication and extended tool life
• HSS material: robust for iron and steel family alloys
• Round shank: compatible with chucks and collets
• Spiral flute design: effective chip removal when cutting

Can I use these taps for both hand tapping and CNC or machine tapping?

Yes — the taps in this set are engineered for hand use but perform well under power when proper tapping technique is followed. They are a common choice for general machine tapping and CNC applications across a broad range of materials. Select the appropriate tap profile and lubrication based on material and thread depth for best results.

• Hand use: ergonomic profiles for controlled starts
• Machine/CNC: suitable with correct feeds, speeds, and coolant
• Material range: designed for ferrous materials and many steels
• Included sizes: M22 x 2.5 tap set matched to 29.50mm drill

Who is this kit for? This Drill America kit is built for machinists, maintenance technicians, fabricators, and hobbyists who need a compact, ready‑to‑use combination for creating M22 x 2.5 threads. It suits shops that want a reliable HSS tap set for through and blind holes plus a durable black oxide drill for pre‑drilling in iron and steel relatives. The small plastic pouch keeps the tools organized for portable jobs or organized storage at the bench.
