OSGTOOL.COM 20 WWW.BHID.COM • 855-610-1001 Counterboring Grey Cast Iron Both A Brand® ADF Drills and conventional drills show little to no positional inaccuracies when processed over the center of a pre-existing hole. However, when it is necessary to process the drill off-center over a pre-existing hole, the position and straightness of the hole made with the ADF is 5 times more accurate than the conventional drill. −X +X +Y −Y −X +X +Y −Y Ø18 2 mm Ø10 Pilot Ø18 Ø10 Pilot Test 1 (Centered) Test 2 (0.0787”O set) 0.0098 0.0059 0.0078 0.0039 0.0019 0.0000 ADF-2D Conventional CarbideDrill AmountofShift inHolePosition (inch) Shift Amount in Hole Position Centered vs Offset −X +X +Y −Y −X +X +Y −Y Ø18 2 mm Ø10 Pilot Ø18 Ø10 Pilot Test 1: Centered Test 2: Offset by 2mm Tool ADF-2D Conventional Carbide Drill Drill Size Ø18 Machined Surface Flat Surface Work Material Grey Cast Iron Cutting Speed 246 SFM (1,327 RPM) Feed Rate 5.2 IPM (0.004 IPR) Depth of Hole 34 mm (Blind) Coolant Water Soluble Machine Horizontal Machining Center Half-Hole Carbon Steel (1050) The ADF minimized the amount of shift when drilling a half-hole as compared to both the conventional and competitor drills.
