Makita BDF452HW Cordless Drill


PERFORMANCE RATINGS
Power 450 in-lbs - The BDF452HW generates about average power and torque when compared to other 18V-class cordless drills. The average cordless drill in this class can generate up to 468 in-lbs of maximum torque.  
Speed
Settings
2 Settings 0-400 / 0-1,500 RPM - Fitted with both Low and High speed settings that come standard on most cordless drills. Speed selection is an important feature to match drilling or driving RPM to each unique job.
Max
Speed
1500 RPM - This Makita cordless drill has about average speed with a max RPM comparable with standard 18V-class drills. The average cordless drill in this class runs at speeds up to 1584 RPM.  
Clutch 16 Settings - The Makita BDF452HW has a below average number of clutch settings, but is probably still adequate for many DIY jobs. The clutch helps you to avoid stripping a screw with too much torque.  
Power
Ratio
129 P/W - The Makita BDF452HW has an 29% higher than average power-to-weight ratio and ranks in the top 20% of efficiently designed 18V-class drills. The P/W ratio is 29 higher than the 100 average ratio for this class drill.
Hammer This cordless drill is not equipped with a hammer function that can deliver several thousand impacts per minute. Hammer drill drivers are usually a little heavier and costlier, but they are effective on tougher jobs such as drilling into concrete.  


DURABILITY RATINGS
Gear
Case
All-Metal - The Makita BDF452HW transmission has all-metal gears that provide superior durability compared to nylon gears found in many drills. Gears spin at high RPMs and are susceptible to material break-down.
Chuck Plastic Sleeve - Chuck sleeves made of tough plastic materials save on weight, but they are more prone to cracking than metal sleeves. It generally won't withstand repeated drops onto hard surfaces.  
Motor External Access Brushes - Motor brushes must be replaced periodically and external access makes the job a much easier DIY task. No need to take your drill into the repair shop for complete disassembly.
Warranty 3-Year - Makita's 3-year limited tool warranty is a little longer than average for the cordless drill industry where the standard is about 2-3 years. Longer warranties can often indicate improved durability with fewer repairs.


BATTERY RATINGS
Type Lithium Ion (Li-Ion) Compact BL1815 - Newer technology rechargeable battery that provides higher capacity and longer run-time with less weight, but are more expensive than the older NiCd and NiMH batteries.
Capacity 1.5 Ah - This Lithium Ion (Li-Ion) battery ranks about average for capacity and run-time with an amp-hour (Ah) rating that is considered standard for 18V-class batteries. The average battery capacity for this class is rated at 2.2 amp-hours.  
Charge
Time
15 min Rapid Optimum Charger - Battery charge-time is quicker than average. Nice feature for those times when you don't have a charged replacement battery ready to go and you're in the middle of a job.
Fuel
Gauge
No Battery Fuel Gauge - Not equipped with a battery charge indicator that alerts you to remaining battery life or if the batteries are running low. Sudden battery failure during the job is a common frustration.  
Backup 2 Batteries Included - It's important to have a second back-up battery for the Makita BDF452HW that's charged and ready to go. Makes it easy to swap-out batteries during the job with minimal down-time.


CONVENIENCE RATINGS
Weight 3.5 lbs Tool Plus Battery - It is 26% lighter than average and ranks in the top 20% of 18V-class drills for lower weight. It weighs 1.2 lbs less than the average 4.7 lb cordless drill in this class and should decrease operator fatigue.
Length 8 in - Cordless drill length is a personal preference, but shorter is generally better to help you in close quarters such as under a sink, or drilling in-between studs. Torque is harder to handle if the drill is too short though.  
Spindle
Lock
One-Hand Bit Change - This single-sleeve chuck has auto spindle lock. The drill bit can be changed with only one hand by simply spinning the chuck open to release the bit, and counter-spinning it to tighten.
LED
Light
Integrated LED Light - The Makita BDF452HW illuminates your work area and allows you to clearly see your bit position and depth while you're drilling or driving. Great feature that's now available on many cordless drills.
Belt
Hook
No Belt Hook - There is no provision to hang the drill on your belt and free-up both hands to perform other tasks. You may be able to purchase a separate belt clip that can be attached to the drill.  
Side
Handle
No Side Handle - Side handles are a great safety feature and should be considered if you plan to drive at higher torque levels. They can help prevent injury by providing increased stability and control.  
Bubble
Level
No Bubble Level - This feature is only available on a few drills and can be helpful in situations where precision holes are critical for alignment. Most projects can be performed with just visual sighting.  
Keyless Keyless Chuck - Nearly all cordless drills are now equipped with keyless chucks that can be tightened with both hands (double-sleeve) or just one hand (single-sleeve) without the use of a key.
VSR VSR - Most cordless drills are equipped with variable speed capability that can be controlled with simple trigger pressure. Reverse is usually performed with the push of a side-to-side button.
