Webb12 apr. 2024 · It is also highly recommended to start off your hole using a same-diameter stub drill to make a pilot hole, usually to 2xD depth. This is particularly important in horizontal boring situations, where even large diameter long drills can ‘sag’ under their own weight, leading to inaccurate holes and potential tool breakage. WebbThe slower spiral helix reduces the aggressiveness of the drill, allowing the operator to maintain control during hand operations. Four margins create stability in the bushing and hole, to produce close tolerance holes. We can manufacture the Double Margin Slow Spiral drill in a single diameter, drill reamer, or drill/drill ream configuration.
