Why We Love It

The features that make this product stand out from the competition.

Open-stock ecosystem

Chapman sells individual bits, handles, extensions and ratchet parts instead of treating the kit as sealed.

Tight-space ratchet

The compact CM-13 supplies a right-angle drive where a normal screwdriver handle cannot clear.

Long-proven format

Chapman says the core mini-ratchet and bit architecture has remained essentially unchanged since 1936.

Frequently Asked Questions

What is included in the #5575 Master Screwdriver Set?

Chapman lists the #5575 as a 56-piece set with 51 insert bits. The listed bit families are slotted, Phillips, metric hex, SAE hex, and star bits that fit Torx screws. The product listing also describes more than 300 tool combinations.

Does this set include a ratchet, and what is its rating?

The #5575 listing identifies an included CM-13 mini ratchet. Chapman rates that ratchet at 200 inch-pounds of torque and describes it as comparable to the torque of four large screwdrivers. It also states that many individual bits have lower torque limits based on the screws they fit.

What construction details does the manufacturer list for the ratchet?

Manufacturer media for this exact set identifies a 1/4-inch-drive, 20-tooth gear for the included ratchet. The same source describes that gear as milled from USA tool steel, heat treated, and finished with black oxide. This describes the ratchet gear, not a universal rating for every component in the set.

Is a spinner component included for work in tight spaces?

The product's manufacturer media identifies a spinner top as included with the #5575. Chapman describes that component as intended for tight spaces or for starting screws. The product listing does not establish that this accessory is needed for every fastener, so its usefulness will depend on the access and screw being worked on.
