Buying Guide

Match reamer size to the hole

Choose the correct nominal diameter (for example 3/4", 13/16" or 7/8") to achieve the final hole tolerance without overworking the part

Check shank compatibility

Confirm the reamer's shank (common 1/2" in these picks) fits your chuck or collet to avoid runout and enhance concentricity

Select appropriate material and geometry

HSS and M2 HSS provide durability for steel and bridge/construction work; 5-flute designs can improve finish and chip control on tougher metals

Consider taper vs straight shanks

Tapered reamers aid in alignment and progressive sizing, while straight chucking reamers are easier to mount in standard drill chucks

Match reamer to application

For hole alignment and finishing in structural work choose reamers specified for bridge or construction use and optimized for metal cutting
