Precise Knurl Wheels

• Knurling wheels are technically designed to knurl against a square shoulder.
• Included Tooth Angle: 90
• Hardness: 58 to 60 RC
• Tin Coated High Speed Steel.
• With super precise workmanship, the wheels are made of heat treated high speed steel to withstand severe knurling operation.
• Reduces the co-efficient of friction when knurling, increasing the quality and the force of knurling as well as the life of the knurl wheels.
• Made in the U.S.A.
