Cutting rate control for an ice drill

1. An ice drill comprising:

a motor;

a drive shaft attached to the motor at a first end;

an auger assembly attached to the drive shaft;

a cutting head attached to a second end of the drive shaft, the cutting head including:

a main body having a top side and a bottom side, the bottom side defining a bottom peripheral surface that defines a first surface configured to be positioned generally parallel to and directly face toward an ice surface during operation of the ice drill without an intermediate structure positioned between the first surface and the ice surface;

a center blade disposed on the bottom side of the main body, wherein the center blade is configured to control lateral movement of the cutting head;

at least one cutting edge disposed on the main body, the cutting edge being configured to perform a cutting operation at the bottom side of the main body; and

at least one cutting rate control pad disposed on the bottom side of the main body, wherein the at least one cutting rate control pad extends away from the bottom peripheral surface;

wherein the at least one cutting edge is spaced away at a first distance, in a direction away from the bottom side of the main body, from an ice interfacing surface of the at least one cutting rate control pad, the ice interfacing surface being configured to contact the ice surface during a drilling operation; and

wherein the first distance is between about 0.180 inches and about 0.220 inches.

2. The ice drill of claim 1 , wherein the auger assembly has a plurality of flights, wherein the flights are configured to alter the length of the auger assembly.

3. The ice drill of claim 1 , wherein the first distance is 0.200 inches.

4. The ice drill of claim 1 , wherein the at least one cutting rate control pad is removable from the main body.

5. The ice drill of claim 1 , wherein the at least one cutting rate control pad is integrally formed with the main body.

6. The ice drill of claim 1 , wherein the motor is an electric motor.

7. The ice drill of claim 1 , wherein the main body includes a blade pad configured to receive a cutting blade having the at least one cutting edge, the blade pad being positioned at the top side of the main body, wherein the blade pad is configured for allowing fine tuning of the position of the cutting blade.

8. The ice drill of claim 1 , further comprising a plurality of cutting rate control pads disposed on the bottom side of the main body.

9. The ice drill of claim 1 , further comprising a plurality of cutting edges disposed on the main body.

10. The ice drill of claim 1 , wherein the at least one cutting edge is a removable blade attached to the main body.

11. The ice drill of claim 1 , wherein the main body includes a pair of wings extending outwardly from a center body, the pair of wings each including cutting edges disposed thereon and cutting rate control pads disposed on bottom surfaces thereof.

12. An ice drill comprising:

a motor;

a drive shaft attached to the motor at a first end;

an auger assembly attached to the drive shaft;

a cutting head attached to a second end of the drive shaft, the cutting head including:

a main body having a top side and a bottom side, the bottom side defining a bottom peripheral surface that defines a first surface configured to be positioned generally parallel to and directly face toward an ice surface during operation of the ice drill without an intermediate structure positioned between the first surface and the ice surface, wherein the main body includes a blade pad positioned at the top side of the main body;

at least one cutting blade mounted to a top surface of the blade pad of the main body, the at least one cutting blade being configured to perform a cutting operation at the bottom side of the main body, wherein the blade pad is configured for allowing fine tuning of the position of the at least one cutting blade; and

at least one cutting rate control pad disposed on the bottom side of the main body, wherein the at least one cutting rate control pad extends away from the bottom peripheral surface;

wherein the at least one cutting blade is spaced away at a first distance, in a direction away from the bottom side of the main body, from an ice interfacing surface of the cutting rate control pad, the ice interfacing surface being configured to contact the ice surface during a drilling operation.

13. The ice drill of claim 12 , wherein the main body is cast metal.

14. The ice drill of claim 12 , wherein the main body includes a pair of wings extending outwardly from a center body, the pair of wings each including blade pads each configured to receive a cutting blade.

15. The ice drill of claim 14 , wherein cutting rate control pads are disposed on bottom surfaces of the wings.

16. The ice drill of claim 15 , wherein the first distance is between about 0.180 inches and about 0.220 inches.

17. A cutting head for an ice drill comprising:

a main body attachable to an ice drill shaft at a top side, the main body including a bottom side having a bottom peripheral surface that defines a first surface configured to be positioned generally parallel to and directly face toward an ice surface during operation of the ice drill without an intermediate structure positioned between the first surface and the ice surface, wherein the main body includes a blade pad positioned at the top side of the main body;

at least one cutting blade mounted to a top surface of the blade pad of the main body, the at least one cutting blade being configured to perform a cutting operation at the bottom side of the main body, wherein the blade pad is configured for allowing fine tuning of the position of the at least one cutting blade; and

a cutting rate control pad disposed on the bottom side of the main body, wherein the cutting rate control pad extends away from the bottom peripheral surface;

wherein the at least one cutting blade is spaced away at a first distance, in a direction away from the bottom side of the main body, from an ice interfacing surface of the cutting rate control pad, the ice interfacing surface being configured to contact the ice surface during a drilling operation.

18. The cutting head of claim 17 , wherein the first distance is between about 0.180 inches and about 0.220 inches.

19. The cutting head of claim 17 , wherein the cutting head is attached to an ice drill, the ice drill including a motor.

20. The cutting head of claim 17 , wherein the cutting rate control pad is removable from the main body.
