Palm head and quill
The top head provides axial pressure while the crank rotates beneath a steady hand. Stanley lists the head and quill as separate repair groups.

An original educational poster identifies 8 documented construction features. The numbered descriptions remain readable below the artwork on narrow screens.
- Palm head
The black head bears steady top-hand pressure while the crank rotates below it.
- Head quill
The short quill seats the rotating palm head on the upper crank end.
- Continuous swept crank
One bent chrome-steel frame provides the documented 10-inch sweep.
- Rotating side grip
Black molded handle rotates around the offset crank span.
- Open-ratchet shell
Compact rear chuck-end group selects or transmits the hand-crank drive.
- Complete two-jaw chuck
The silver chuck assembly is separate from the ratchet end; its two visible jaw tips grip the bit tang.
- Square-taper tang
The four-sided tapered tang seats in the two-jaw brace chuck.
- Solid-center auger
The lead screw starts the hole; cutting lips and the single flute cut and clear wood.
Technical references: Stanley 02-660 manufacturer product catalog · Stanley RP402 repair parts catalog, 02-660 · ICS solid-center auger catalog, AB032. The maker's repair catalog lists separate head, quill, chuck assembly, and jaws-and-spring groups. The study separates the visible head, complete chuck and auger, while keeping the one-piece crank and rotating grip together and showing the two jaw tips in the chuck mouth. Original educational artwork depicts documented component groups and their relationships; it is not a service sequence or a replacement for the exact model manual.
02 / Understand the tool
What it is and what each part does
The archival Stanley 02-660 product catalog specifies a 10-inch sweep, molded polypropylene head and side handle, open ratchet and alligator jaws. Its repair-parts catalog separately identifies the head, quill, chuck assembly, jaws and spring, and ratchet parts. The illustrated companion is an ICS AB032 solid-center hand-brace auger with a tapered square tang, one flute, a lead screw, cutting lips and outlining spurs. Its bit shape and shank are matched to a traditional two-jaw brace; verify actual fit before use.
Pressure on the palm head holds the lead screw on the mark while the other hand rotates the one-piece swept crank through its side grip. The chuck jaws grip the square-taper tang; the lead screw feeds the bit, and cutting lips, spurs and the single flute cut and clear wood. The construction study spaces the auger, whole chuck assembly and palm-head/quill group from the continuous crank to explain their relationship. It does not claim a detailed ratchet or bearing service sequence.
Swept steel crank
The 10-inch sweep gives manual leverage and clearance; the rotating side grip allows continuous turning.
Two-jaw chuck and open ratchet
Opposing alligator jaws clamp a fitting square-taper tang. The compact ratchet end transmits the crank's motion; confirm secure bit seating before applying torque.
Solid-center auger
A square-taper tang, lead screw, outlining spurs, cutting lips and single open flute bore a hole and move chips upward.

Set, guide and control the action
These decisions make the mechanism useful at the bench.
Match bit to chuck
Check the square-taper shank against the brace's alligator jaws, then seat and tighten the bit securely.
Guide from two directions
Keep the lead screw at the mark and sight the shaft square to the chosen reference face from two sides.
Clear chips gently
Withdraw periodically in deep holes. Stop if torque rises rather than forcing a jammed auger.
Bore for joinery
Drill a controlled hole for a tenon, peg or hardware layout where low speed helps placement.
Work without power
Bore at a bench or site without a motor while keeping tactile feedback as the cutter enters.
Deep timber holes
A suitable long auger can reach through substantial stock if its length and diameter match the work.

Setup, technique and finish quality
Use the steps for a first pass, then inspect the work before changing the setup.
- Mark the center with an awl and clamp the work over a sacrificial backer.
- Choose a bit whose diameter, length and shank suit the work and the brace chuck.
- Open the two-jaw chuck, fully seat the shank and tighten it without cross-clamping.
- Place the lead screw in the center mark, apply steady palm pressure and sight square from two directions.
- Turn the crank smoothly; clear chips by backing the bit out as needed.
- Ease feed before breakthrough, or bore from both sides when the exit face must remain clean.
Leverage over speed
A 10-inch sweep supplies torque at slow hand speed, which helps control a large auger.
The bit does the feeding
The lead screw pulls the cutter in; excessive top-hand force can split fibers or bind the bit.
Documented construction groups
Changing the bit is ordinary operation. Stanley's repair catalog also identifies separate head, quill, chuck and jaw groups; the study shows only visible group relationships, not a service order.
What changes by model or material
A smaller sweep works in tight spaces; a larger sweep offers more leverage. Compare exact brace models.
Two- and four-jaw chucks have different shank ranges; verify compatibility rather than assuming every bit fits.
Single- and double-flute designs, lead-screw pitches and spur shapes vary by manufacturer and wood.
Choosing the tool
- Check smooth head and side-grip rotation, undamaged chuck jaws, and a crank without wobble.
- Select a sweep that fits the work area and expected bit diameter.
- Check each auger shank against the actual chuck and inspect its lead screw, spur and cutting lip.
Useful accessories
- Awl or center punch
- Sacrificial backer
- Bit guard and storage roll
Consumables
- Light lubricant for exposed steel
- Sharpening file matched to the bit geometry
04 / Keep control
Care, troubleshooting and safety
Secure the work, protect sharp edges and release any stored clamping pressure before adjustment or maintenance.
Care checklist
- Brush chips from the chuck and auger flute after use.
- Dry and lightly protect exposed steel from rust.
- Store bits so lead screws and cutting lips cannot strike one another.
- Keep head and grip bearings clean; follow maker guidance before adding lubricant.
Common mistakes
- Clamping an oversized or mismatched shank.
- Leaning hard enough to skew or jam the hole.
- Failing to support the exit face.
- Sharpening the outside of a spur and changing hole diameter.
Safety at the operation
- Clamp the work; keep the support hand away from the exit path.
- Wear eye protection against chips and protect sharp bit tips in storage.
- Stop and withdraw a bound bit; avoid sudden crank release.
- Check hidden services before boring into installed work.
When the result goes wrong
Stop, clear the jaws and verify that the shank actually matches the chuck's capacity.
Recheck the starting mark, pressure and alignment from two directions; use a sharp lead screw and spur.
Withdraw and clear the flute more often; reduce feed in damp or resinous wood.
