Questions about this item
How do I install the No 40 drill in a chuck without damaging the shank?
Tighten the chuck jaws evenly around the shank of the 30509800AM drill so the flutes remain clear of the jaws; the step people get wrong is over-tightening on the fluted section instead of the smooth shank.
What maintenance will the No 40 drill need after repeated use?
Inspect the cutting edges for wear and resharpen using a drill sharpener set to the original point angle; replace the drill when the diameter falls below the No 40 size.
What limit appears first when drilling continuously with the No 40 drill?
Heat buildup at the cutting edges is the first limit; use cutting fluid and reduce feed pressure to keep the 30509800AM drill within its working temperature range.
