Precise Precision Boring Heads

• A micrometer lead screw provides 0.001 for 2 b boring head or .0005 for 3 & 4 boring head direct reading accuracy and ease of adjusting.
• Double bar holder permits a greater boring range without an extreme offset condition.
• Made of 20CrMnTi alloy steel.
• Compared to generic 2: & 3 boring heads on the market, the main lead screw has minimum amount of backlash in 5-10 graduation while the generic model has around 12-20 graduation. Smaller backlash allows the operator to be able to dial in on the desired level much easier.
