Questions about this item
Will the 135-degree split point on these Irwin 63113 bits reduce walking when I use them with my older drill press?
The 135-degree split point is designed to start on contact and reduce walking, which helps maintain accuracy on older drill presses that may have more runout.
How can I confirm the 135-degree split point is performing correctly after I start drilling?
A properly working split point will centre itself immediately without a centre punch and produce a clean, round hole with minimal burr on breakthrough.
