This video provides a detailed comparison between impact drivers and drills, explaining the key differences and when to use each tool. The video begins by discussing the most significant difference: the spinning chuck on the drill that doesn't have any special features, while the impact driver has a different driving mechanism. The drill has a variable speed controlled by the trigger and gears, while the impact driver typically only uses the trigger to control its speed.
The video then discusses the impact driver's ability to switch between different modes, including a self-tapping screw setting, which the drill lacks. It also highlights the impact driver's requirement for a quarter-inch hex bit, unlike the drill which can accommodate a range of bit sizes.
The drill's clutch feature, which allows for varying levels of resistance, is another feature not present in the impact driver. The video also notes the drill's gears, which allow for more control over speed and torque, a feature not available in the impact driver.
The video also discusses the size difference between the two tools, with the drill being significantly longer and taking up more space. This can be a significant factor when working in confined spaces.
The video concludes by discussing the impact driver's ability to act like a ship's wheel, providing rotational impact to drive the bit. It explains how the three parts of the impact driver - the hammer, spring, and anvil - work together to provide this impact.
The video also addresses the noise level of impact drivers, noting that while they are louder than regular drills, some models offer quieter operation.
Finally, the video provides some practical examples of when to use each tool. It suggests using an impact driver for tasks like drilling holes in electrical work or for tasks that require driving in, and a drill for tasks like creating holes for fasteners or when more control over speed and torque is needed.
The video ends by emphasizing that both tools can be used together for most jobs, highlighting their complementary roles in different tasks.
Here are the key facts extracted from the text:
1. The chuck on a drill spins in one direction and doesn't have any special features inside.
2. An impact driver has a totally different driving mechanism than a drill.
3. A drill typically has two things that control the speed: the trigger and the gears.
4. An impact driver usually only has a trigger to control the speed.
5. Some impact drivers have additional features such as multiple speed settings and self-tapping screw settings.
6. A drill has a three-jaw chuck that allows for different drill bits to be used.
7. An impact driver requires the use of a quarter-inch hex bit.
8. Drill bits for impact drivers should have a special indentation and a thinner torsion zone.
9. A drill has a clutch that allows for controlled resistance when driving screws.
10. An impact driver does not have a clutch and will continue to drive screws until they are stripped.
11. Drills often have a hammer mode for drilling into hard materials like concrete or rock.
12. Impact drivers are not suitable for drilling into hard materials.
13. Drills are generally longer and take up more space than impact drivers.
14. Compact sets of drills and impact drivers are becoming popular due to their smaller size.
15. Impact drivers can experience kickback, but some manufacturers are introducing anti-kickback features.
16. The impact mechanism in an impact driver uses a hammer and anvil to generate rotational impact.
17. The difference in torque between a drill and an impact driver is significant, with impact drivers typically having more torque.
18. Impact drivers are often louder than drills due to their impact mechanism.
19. Some impact drivers, like the Milwaukee Surge, use a pneumatic impact driver and are significantly quieter than traditional impact drivers.
20. Drills and impact drivers can use the same batteries interchangeably.
21. Both drills and impact drivers have forward and reverse mechanisms.
22. Some drills and impact drivers have a lock mechanism that prevents the trigger from being used.
23. Impact drivers can be used to drill holes in certain situations, such as with electrical work or when using self-feeding bits.
24. Drills are generally better suited for drilling holes with forstner bits, hole saws, metal drilling, and spade bits.
25. Makita and other brands make converters that allow a traditional three-jaw chuck to be used in an impact driver.
26. Using both a drill and an impact driver is often the best option, as they complement each other's strengths and weaknesses.
