Drill Press Q&A

---

1. Why is a drill 'backed out' after before it finishes drilling a hole with a 1:1 aspect ratio?

   A) So that the operator can add cutting fluid to the hole.

   B) So that a larger drill can be installed on the press.

   C) So that chips generated by the drill can be cleared away.

   D) So that the operator can change the speed of the drill.

2. The noise caused by a deflecting drill is:

   A) binding

   B) chattering

   C) grinding

   D) burring

3. What action should you take when this noise occurs even at low drilling speeds?

   A) Change the transmission ratio of the drill.

   B) Add more cutting fluid to the hole.

   C) Increase the speed of the drill.

   D) Replace the existing drill with one made of hardened steel.

4. If you attempt to use a drill press as a milling machine, you run the risk of:

   A) damaging the milling tools.

   B) damaging the quill of the drill press.

   C) creating parts with dangerously sharp edges

   D) creating parts with unacceptable surface finishes

5. The depth guage is used in conjunction with which function of the drill press?

   A) High drilling speeds

   B) Step-shank drills

   C) Power feed

   D) A sensitive chuck

6. What part of the drill allows the chips to be drawn out of the hole during the drilling process?

   A) bit

   B) flute

   C) flat

   D) shank

7. The best way to drill the roundest possible hole is by:

   A) gradually stepping up drill sizes.

   B) gradually decreasing the speed of the drill.

   C) using the hardest drills available.

   D) using a reamer.

8. What is the main advantage of the sensitive chuck?

   A) Its ability to move in the X/Y direction while drilling.

   B) It holds drills upwards of 1" in diameter.

   C) It eliminates drill noise.

   D) Its ability to be moved up and down by the operator's hand.

9. All of the following are advantages of small drill presses, except:

   A) high speeds.

   B) a stationary motor and chuck.

   C) a stationary bed.

   D) greater sensitivity when using small drills.

10. The primary function of a high helix angle in a drill is to:

    A) draw chips out of the hole.

    B) reduce drill noise.

    C) allow drilling at high speeds.

    D) drill the roundest possible hole.

11. On which of the following materials would a drill with a high helix angle be ineffective?

    A) aluminum

    B) brass

    C) wood

    D) steel

12. For abrasive materials, the best drill to use is one made out of:

    A) hardened steel

    B) tungsten carbide

    C) brass

    D) stainless steel

13. The largest hole size that can safely be drilled by the press demonstrated here is:

    A) 1 inch

    B) 1.5 inches

    C) 2 inches

    D) 2.5 inches
