   Size Units:       
   Your choices are...         
   English / Fractional       The reamer is designed with base units of inches or fractions of an inch. 
   Metric       The reamer is designed with metric base units such as millimeters or centimeters. 
   Wire Gauge       The reamer is fashioned in standard wire gauge sizes, designated 1 to 80. 
   Letter Size       The reamer sets in standard letter designation sizes from A to Z. 
   Other       Other unlisted size series or units. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Cutting Diameter:       This refers to the full tool cutting diameter. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Set Size Range:       The set size rang refers to the smallest-to-largest reamer size included in the set. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Reamer Type       
   Your choices are...         
   Chucking Reamer       Chucking reamers are the most common reamer type, and are used for general-purpose reaming. Chucking reamers typically come with a straight shank. Standard sizes include all common English and metric sizes, wire gauge, and number / letter designations. 
   Jobber Length Reamer       Jobber length reamers are common industrial configurations that have somewhat longer flutes and overall length than standard chucking reamers. 
   Taper Pin Reamer       Taper pin reamers are ground with a standard taper, most commonly 1/4" per foot, for fitting pins with the standard taper. 
   Taper Pipe Reamer       Taper pipe reamers are used to prepare holes for being tapped with a standard pipe thread.  NPT standard tapers are 3/4" per foot. 
   Hand Reamer       Hand reamers are tools for manual reaming; they are typically equipped with a handle. 
   Bridge Reamer       Bridge reamers are heavy-duty reamers used for construction, shipbuilding, and other heavy industrial applications. They are often used for alignment of holes for rivets or other structural fasteners. Bridge reamers are named for their use on the structural steel of bridges and other structures. 
   Car Reamer       Car reamers are somewhat shorter than bridge reamers, but are also meant for heavy-duty use in structural work. They are named for their use for hole alignment and repair in railroad cars. 
   Morse Taper Reamer       The reamer is tapered with a standard Morse taper. 
   Repair Taper Reamer       Repair reamers are commonly used in utility and maintenance applications. 
   Shell Reamer       Shell reamers mount onto an arbor; the mounting hole often has a taper to match the arbor. Shell reamers are often interchangeable so that the arbor can remained chucked; one arbor can typically accommodate many sizes of shell reamers. 
   Deburring Reamer       Deburring reamers are designed to remove the burrs left from other cutting operations, such as drilling or milling. 
   Step Reamer       Step reamers have incrementally increasing diameter steps. 
   Center Reamer       Center, multi-flute reamers are used to create or finish countersinks in holes; they often come in standard angles to accommodate countersinks for flat head machine screws. 
   Dowel Pin Reamer       Dowel pin reamers are slightly undersized for finishing holes into which dowel pins will be pressed. They typically range from 0.0005" to 0.0020". 
   Extended Length Reamer       Extended length reamers are extra long flutes for deep hole reaming. 
   Reamer Blank / Semi-Finished       Reamer blanks are used for grinding standard or specialized cutting edges and flute geometry. 
   Other       Other unlisted, specialized, or proprietary reamers. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

   Flute Style:       
   Your choices are...         
   Straight       Straight flutes are common industrial configurations that are parallel with axis of hole being reamed. 
   Spiral       Spiral or helical flutes can aid in finish quality and chip evacuation in deep holes; they are also used where the hole is not continuous. 
   High Helix       High helix flutes are specialized to increase shear cutting and enhance chip removal. 
   Right Hand Spiral / Helix       Flutes are spiraled in the right-hand direction. 
   Left Hand Spiral / Helix       Flutes are spiraled in the left-hand direction. 
   Other       Other unlisted, specialized, or proprietary flute geometry.

Construction
           
   Your choices are...         
   Solid Construction       The drill is manufactured from a solid piece of material. 
   Bonded Tips       Cutting tips or edges, such as carbide tips, are permanently bonded on a steel shaft. 
   Holder and Inserts       The drill is constructed with a holder with attachable inserts; these inserts typically bolt onto the holder and are replaceable when the cutting edges are worn. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Material       
   Your choices are...         
   High Speed Steel       High speed steel is a cost-efficient cutter material used for general application metal machining. 
   Cobalt       Cobalt steel reamers are somewhat harder than high-speed steel and are often used for drilling in stainless steel and other alloys. 
   Carbide       Carbide grades are much harder than high-speed steel, and therefore last longer and wear less.  Several coatings are available to lengthen cutter life. 
   Diamond / PCD       Industrial diamond grades are used for longevity, and sometimes for special applications such as very high-speed cutting; examples include polycrystalline diamond (PCD) 
   Other       Other unlisted or specialized cutter material. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Coating / Finish:       
   Your choices are...         
   None       The reamer has uncoated cutting edges. 
   Coated       Reamer has a coating to assist in cutting lubricity and/or add abrasion resistance for longer tool life. 
   TiN       Titanium nitride is widely used general-purpose tool coating and in most cutting operations. It provides good adhesion and low friction; it is typically pale gold in color. 
   TiCN       Titanium carbon nitride provides good hardness and smoothness, and is often used on drills and reamers for castings and nonferrous materials. This coating is often bluish-gray in color.

   Reduced Shank       The shank mounting diameter is reduced from cutting diameter, often for mounting in a smaller or standard-size chuck. 
   Hex Shank       The mounting portion of shank is hexagonal in shape for positive-hold mounting in a chuck. 
   Square Shank       Square shanks are used for handles, wrenches, or vise engagement. 
   Threaded Shank       The shank is threaded for screwing into the mounting arbor. 
   Other       Other unlisted, specialized, or proprietary shank style. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
