Drill America 1/14" Cryogenic Treated HSS Black & Gold KFD Split Point Jobber Length Drill Bit | CRYKFDPRO1/4

Meets the requirements of Ford

Product Overview

The Drill America 1/4" Cryogenic Treated HSS Black & Gold KFD Jobber Length Drill Bit (SKU/MPN: CRYKFDPRO1/4) is a heavy-duty, industrial-grade cutting tool engineered for demanding metalworking applications. Part of the KFD (Killer Force Drill) series, this bit is manufactured from M2 premium-grade high-speed steel (HSS) and undergoes an intensive cryogenic treatment process where it is frozen to -300°F for 48 hours.

This deep-freeze thermal processing fundamentally alters the metallurgy of the steel, increasing its surface hardness to 70 Rockwell C to significantly reduce breakage, chippage, and premature wear. Engineered to cut faster, last longer, and produce smoother holes than standard drill bits, it serves as a cost-effective alternative to cobalt bits when drilling tough alloys and 300/400 series stainless steel.

Key Features

• Cryogenic Treatment: Deep-frozen at -300°F for 48 hours to dramatically increase tool life, wear resistance, and structural stability, achieving a hardness rating of 70 Rockwell C.

• M2 Premium HSS Construction: Crafted from high-grade M2 high-speed steel for exceptional durability and cutting efficiency.

• 135-Degree Split Point: Self-centering point geometry starts drilling immediately on contact without walking or wandering across the workpiece.

• 3-Flat Shank: Features three precision-machined flats on the shank to eliminate bit slipping and spinning inside drill chucks under high torque loads.

• Black & Gold Surface Treatment: Specialized finish formulated specifically for drilling stainless steel and hard metals, aiding in lubricity and heat reduction.

• Cobalt Alternative: Delivers high-performance cutting capabilities that allow it to be used in place of traditional cobalt drill bits when machining abrasive stainless steels.

Technical Specifications

Ideal Use Cases & Compatible Materials

The Drill America KFD Cryogenic bit is tailored for high-stress drilling across a broad spectrum of hard metals and alloys:

• Stainless Steel: Specifically engineered to be used in place of a cobalt drill bit when drilling 300 & 400 series stainless steel.

• Ferrous & Non-Ferrous Metals: Excels in cutting alloy steel, aluminum, brass, bronze, carbon steel, spring steel, tool steel, and other metals.

• High-Torque Applications: The 3-flat shank is designed to prevent spinning inside drill chucks. This positive grip ensures maximum power transfer from the tool to the workpiece during heavy drilling operations.

Common Questions (FAQs)

Q: What does "cryogenic treatment" do to this drill bit?
A: Cryogenic treatment involves freezing the M2 high-speed steel drill bits to -300°F for 48 hours. This deep-freeze thermal processing prevents breakage and chippage while raising the overall surface hardness to 70 Rockwell C. As a result, the bit cuts faster, lasts longer, and produces smoother holes than standard drill bits.

Q: Why is a 3-flat shank beneficial? 
A: Standard round-shank drill bits can slip or spin inside a 3-jaw drill chuck when encountering heavy resistance or high torque. The 3-flat shank provides three flat contact surfaces designed specifically to prevent spinning, ensuring secure chuck engagement and consistent rotational power.

Q: Can this 1/4" bit really be used instead of a cobalt drill bit?
A: Yes. Due to its M2 premium grade high-speed steel base, 135-degree split point geometry, and cryogenic hardening reaching 70 Rockwell C, this bit can be used in place of a cobalt drill bit when drilling tough materials like 300 & 400 series stainless steel and other hard metals.
