Alfa Tools offers Blitz Nitride jobber drills for heavy-duty production work, as well as tough maintenance (MRO) applications. These extra heavy-duty drills can tackle applications in the widest range of materials, including mild steel, stainless steel, titanium and nickel alloy steels, as well as nonferrous materials.

Blitz Nitride drills are made from premium M-7 molybdenum HSS with a special nitride treatment to give additional hardness to the cutting edge that lasts longer and outperforms cobalt tools, according to the company. The black oxide and silver finish increases lubricity and reduces friction. The strong web construction provides greater strength and rigidity to get through hard-to-drill materials like stainless steel and titanium alloys.

"Heavy-duty drills are essential to production and the MRO professional," said Shaan Ahluwalia, vice president of sales and marketing at Alfa Tools. "Our Blitz Nitride jobber drills are resistant to wear, which ultimately means the end user gets the lowest cost per hole drilled."

The split point and flute geometry make the Blitz Nitride drills cut cleanly and accurately with less effort, reducing user fatigue. These drill bits also withstand a high degree of heat at high speeds, which reduces friction and enables balanced cutting action with close hole tolerances. The precision-ground 135° split point is self-centering and reduces thrust for more efficient drilling.

Blitz Nitride jobber drill bits are available in steel indexes from 1/16" – ½" in 64th increments. Alfa also offers 13-, 15-, 21- and 29-piece sets. Additionally, they are available in a 29-piece plastic drill mug set.
